Theme parks have mastered queue lines.   Let's talk about how - a video 
collaboration with Jan Walsken,   Research Assistant at the Chair of Logistics 
and Services Management from WHU, Germany. We’ve all come to expect at least one thing 
from a visit to a theme park - queues. The idea   of waiting a substantial amount of time to ride 
your favourite attraction isn’t unfamiliar. You   wouldn’t choose to wait an hour to buy some milk, 
or actively choose to sit in standstill traffic   for an hour - so why do we decide it’s okay to 
queue an hour for rides and roller coasters?   If the wait time itself was the only factor 
involved in people’s enjoyment of a ride, everyone   would hate Disney - their most popular rides 
consistently have hour-long queues! Fortunately   for Disney however, we don’t hate them. Disney, 
and many other theme parks across the globe   have become masters at designing queue lines 
- ones that we all don’t mind waiting within.   In some cases, people are willing to spend three 
hours queueing for a ride, a ride which could last   as little as a few minutes. So, how do they do it, 
how do they get everyone to be okay with queues? Step 1: Queue entrance
Step 1 to creating the perfect   queue line is a memorable entrance. Here, 
first impressions matter. Unsurprisingly,   the most memorable parts of the queuing 
experience are the beginning and the end.   Before we enter a queue for a ride, a list 
of questions usually race through our heads: How long does the queue look?
Is the ride worth the wait?  How does this queue compare 
to other rides in the park? To help us answer these questions, theme 
parks usually provide wait-time estimates,   either as a display at the ride’s entrance, or via 
an app. These estimates are there for a reason,   they actually enhance your overall experience. 
Firstly, approximate measures of queue times cause   people to rethink their decisions. If you walk up 
to a ride and see an excessive queue time, you may   feel obliged to turn away. Over time, this limits 
the length of the queue, keeping wait-times down.   Some parks also employ pessimistic queue times, 
ones which are longer than the real wait.   Generally, we’d much rather find out that 
we’ve waited less time to board the ride,   than more time. This almost gives us a sense 
of achievement, the feeling that you’ve won,   rather than lost out. On top of this, knowing the 
approximate wait time also mentally prepares us   for the wait. Queuing for an unknown amount 
of time can feel long, even if it isn’t. Ultimately, the decision to join 
the queue comes down to value.   For some rides we’re willing to wait excessive 
amounts of time, like at Disney, while for other   attractions we wouldn’t want to wait long at 
all. This generally happens with new rides,   as everyone wants to experience the theme 
park’s newest roller coaster for example,   and therefore it’s perceived value is higher. 
This idea of value also works in reverse.   If you’re unfamiliar with the rides at a 
park, you may unknowingly use queue times   as an indication of how good each ride actually 
is. A roller coaster with a short queue could   be perceived as having less value, so you’d 
naturally gravitate towards the busier rides. A ride’s entrance should help its perceived 
value. A large, extravagant beginning to the   queue is both memorable and impressive, making 
the attraction seem better. Many regional american   theme parks use large ride signs to attract guests 
to the ride’s entrance - the bigger the sign,   the more impressive the ride, at least 
that’s what they want you to think. Step 2: The Queue Layout  No one particularly likes queuing, but we don’t 
mind it as much when the queue is constantly   moving. Theme parks have developed ways to make 
the queues move quicker, or more importantly,   appear as if they’re moving quicker. Making 
physical progress towards the end of the queue   makes wait times seem shorter, especially compared 
to standing still for excessively long periods.   Queues often use corners to make them appear 
smaller - compare one single straight line to a   line with a few turns - at first glance the latter 
looks shorter even though it’s the same length. Another aspect of the queue line at theme parks’ 
disposal is it’s width. The wider the line,   the less space groups of people take up. To give 
the perception that the queue is moving faster,   parks can make the line narrower. This seems 
detrimental, but consider what happens when   a group finishes queuing. The entire line 
moves forwards more if the queue is narrow,   giving you the feeling that 
the line is moving quicker.   Though, a balance must be had. We all appreciate 
personal space, especially when waiting in line,   so this trick isn’t used all of the time. The 
perception of both time and progress is important.   Well designed queues will remove objects 
that convey how much time has passed,   such as a TV that loops the same 10 minute video, 
or a song that restarts every 5 minutes. These   things become repetitive, allowing you 
to acknowledge how much time has passed. Not all queues can be designed perfectly however. 
Theme parks have a finite amount of space for   each ride, space in which the queue line needs to 
fit. To pack as much queue into as small a space   as possible, some parks use a cattlepen, known 
as single serpentine lines to queuing experts.   No one really likes cattlepens, for good 
reasons. They often feature rows upon rows   of adjacent lines, causing you to traverse 
up and down the line, seemingly endlessly.   These single serpentine lines 
break two fundamental rules.   One, they remove everyone’s personal space, 
placing people as close together as possible,   and two, they make it impossible to determine 
progress. You’re stuck for what feels like   years travelling up and down a small patch of 
queue line, not really going anywhere. To make   matters worse, emotions within queue lines can 
be contagious. Unhappy and frustrated guests in   one part of the queue could spread through the 
line, making the experience worse for everyone. In queue lines, it’s very easy to become 
frustrated. We’ve all been waiting in a long queue   and have experienced people shoot to the front in 
the fast pass lane. It’s not unheard of for some   guests to pay money to reduce their wait time, but 
seeing them make more progress than us is simply   frustrating. Theme parks can try to hide their 
fast-track-esque lines from the regular queue,   so guests don’t feel cheated. On many rides this 
is achieved through a merge-point, a place where   the two lines come together, close to where you 
board the attraction. Theme parks also aim to have   the smallest number of queue lines possible. To 
reduce wait times, some rides and roller coasters   feature two loading platforms. Parks often split 
the main queue at the last possible moment,   allowing one to filter to each platform. If these 
were two separate queues from the entrance, guests   would constantly be frustrated that the other 
queue is moving faster - even if it perhaps isn’t. Step 3: The Queue Design
There’s more to queue design than   just the layout however. The best theme parks have 
learnt that keeping guests stimulated in the queue   provides both a better overall ride experience. 
Firstly, many rides and roller coasters use   interaction to make the wait more exciting. The 
queue line might flow next to, above, below,   or around part of the ride’s track. That way, 
while waiting, you watch the attraction you’ve   queuing up before. You see guests hurtling around 
the track, screaming their heads off, all of which   builds anticipation and makes you more excited. 
When it comes to the actual ride, it feels more   exhilarating. Being in the right mental state 
before experiencing an attraction can improve   your enjoyment of it. Naturally, if the queue line 
is empty, you might not get a chance to build up   this anticipation, or absorb your surroundings 
- diminishing aspects of the overall experience.  For many theme parks, considering the 
overall ride experience is a crucial step   in attraction design. To further involve guests 
within their rides, the best theme parks often   attach a storyline to their attractions. This 
story is told through theming and decorations,   placed around the ride area, including the 
queue line. Having a well decorated ride   is more visually interesting and engaging to 
guests. Compare Disney’s Star Wars themed land,   Galaxy’s Edge, to a roller coaster built on a 
flat piece of land - there’s no competition.   Disney theme parks in particular aim to take this 
one step further by transporting guests into an   alternate world, placing them within the story. 
Prior to boarding Millennium Falcon Smugglers Run,   a themed ride within Galaxy’s Edge, guests get 
to board the famous Millennium Falcon ship.   They spend time roaming around the vessel, 
taking in the details, building anticipation.   Riders then move into the ship’s cockpit, before 
beginning the actual ride experience. This all   works together to immerse guests within the Star 
Wars story, making them one of the characters. Other queue lines use interactive elements 
to keep guests engaged. Upon its debut,   Disney’s Seven Dwarfs Mine Train ride featured 
a game guests could play within its queue line.   The game saw visitors sort gems using interactive 
touch screens accessible from both sides of the   line. Disney hoped this would help occupy guests 
while they wait to experience the roller coaster.   The concept worked, as intended, but it wasn’t 
without its flaws. Some guests became too   engrossed within the game and held up the queue, 
ultimately making others frustrated. As a result,   Disney has since removed this interactive 
element from the Seven Dwarfs queue line. To create a completely immersive experience, we 
need more than just visual stimulation. Many theme   parks around the world, even ones outside 
of the big names of Disney and Universal,   use themed audio to help draw guests into a 
ride’s storyline. Music is fantastic for setting   the scene and is quick to influence the mood of 
guests. Fast paced music can build excitement,   psyching us up for the ride; while 
slower soundtracks create anticipation,   and perhaps even make you slightly nervous. 
Likeable music, one which isn’t repetitive,   can actually help to reduce the dissatisfaction of 
queuing for a ride. To achieve this, parks create   soundtracks with no beginning, middle or end, to 
keep the music fresh throughout even long waits. Some theme parks even take it one step further 
and utilise another one of our senses, smell.   Smell pods can be found in a range of 
rides and roller coasters around the world,   further helping to transport guests into the 
world created by the designers of the attraction.   Scent affects our mood subconsciously, 
and helps to stimulate our senses.   Some rides employ smells of damp air, to create 
the illusion that the building guests are waiting   inside is old and weathered. Interestingly 
though, the combination of both music   and scent can be too much for our 
senses, causing them to be overwhelmed. Step 4: Dealing with uncertainty
One of the worst things about waiting   in a queue line is uncertainty. Being told your 
flight is delayed, but not being told by how long,   is incredibly frustrating. Similar experiences can 
happen at theme parks, where rides find themselves   unexpectedly delayed due to technical issues. 
When this happens, the uncertainty makes the   wait seem even longer. First, you notice that 
the ride is no longer sending out new trains,   or that the queue isn’t moving anymore. Then, 
you start to become agitated and thoughts of   “what’s wrong with the ride, is it broken” begin 
to propagate through the queue. To combat this,   theme parks often attempt to update their 
guests if an unexpected delay does occur.   Simply explaining why there’s a delay can 
reduce people's frustration with queuing   significantly. Furthermore, giving an 
approximate duration for the delay,   even if it’s wildly inaccurate, can also 
set people’s mind at ease. Ultimately,   we’re all much happier to queue when we’re 
informed - we just want to know why we’re waiting! Step 5: End of the line
The end of the queue marks the beginning of the   ride. The last few steps of the queue should make 
you feel excited to ride your chosen attraction.   Rides that achieve this often greet you with 
expansive and well themed station buildings,   impressing you moments before boarding. 
Other attractions use pre-shows, short   videos or animatronic audio-visual experiences, 
to further explain the story of the attraction and   build anticipation. The preshow on Disney’s Tower 
of Terror is a well known example, where you find   yourself bundled into a themed room, while an 
old TV sets the scene and further establishes the   ride’s storyline. Other attractions take advantage 
of ride hardware to create a memorable end to the   queue. Disney’s Rock ‘n’ Roller Coaster features 
a launch, which propels guests to 92kmh 57mph   at the very beginning of the ride. The final part 
of the queue sees you walk adjacent to the start   of the launch, forcing you to witness riders 
shoot off into darkness at high speeds. This is   a fantastic way to quickly build anticipation, 
and to make the entire experience memorable. Ultimately, the end of the queue line 
can define the entire waiting experience.   If the queue becomes slow at the end, guests 
may perceive the entire wait as being longer   than they had anticipated, reducing 
satisfaction. Theme parks can cause   the impression that the end of the line 
is moving faster by making it narrower,   causing you to move forward quicker 
than before. A quick end to the queue,   matched with an exciting and grand finale, 
simply makes the wait seem more worthwhile. Step 6: Boarding  The final step before you get to experience the 
ride - board the ride vehicle. The quicker you   board the attraction, the sooner you can be sent 
around the track, allowing more people to board.   Ultimately, theme parks can reduce wait 
times by increasing the capacity of their   attractions - the more guests that ride every 
hour, the shorter the queue time - simple. As   a result, parks will do anything to improve 
the speed at which you board the ride. One method they use is to make sure you know 
how to board the ride before you actually   have to board the ride. Some 
parks use in-queue videos   that explain the boarding process, to 
reduce problems when the time occurs.   These videos are often found on rides with 
quirky ride vehicles, such as Hagrid’s   Magical Creature Motorbike Adventure at 
Universal Studios Islands of Adventure. However, it’s not just guests boarding that 
can slow things down, but also passengers   leaving the ride vehicles. For you to board, 
the other guests must first leave. As a result,   theme parks often open the air gates, 
the gates blocking guests from boarding,   before riders have left the vehicles. This 
causes those waiting to naturally ‘push’   passengers out of their seats quicker than 
normal. This action is exaggerated by narrow   air gates - the small space is not somewhere you 
want to be for long. The entire boarding process   is also sped up by having guests board 
and disembark from the ride on different   sides of the station. This ensures the ride’s 
platform doesn’t become overwhelmed with guests,   all trying to do different things. Some 
attractions get rid of this process altogether   by utilising separate loading and unloading 
platforms. Passengers who’ve just experienced   the ride exit at a separate part of the station, 
meaning an empty vehicle is presented when you go   to board. This reduces loading times, improves 
the ride’s capacity and brings down wait times. No matter what methods theme parks 
employ however, guests frustrated   with their wait can sometimes board slower 
than normal - ruining the entire system. Conclusion  Theme parks have come a long way since their 
inception. The queue used to be an annoyance,   something inevitable before you get to experience 
a ride. However, parks have begun to change the   way we look at queue lines. Interactive elements, 
highly themed details, music, preshows and a whole   host of other things have helped to integrate 
the queue into the overall experience. For guests   to be entirely impressed by a ride, they 
must first be impressed by the queue line. Next time you visit a theme park, take 
note of the measures they employ to keep   you happy while waiting. Does the queue feature 
music? Did you wait less time than estimated?   Could you see any other, alternate queues nearby? 
Soon, you’ll quickly be able to spot a bad queue,   ones with tight cattlepens and repetitive 
televisions. What’s worse than a bad   queue? Knowing you have to queue in a bad 
queue. Perhaps theme parks will abolish   queue lines altogether - instead implementing 
virtual waits. We’d love to hear your thoughts   on queue lines in the comments below. Thank you 
for watching, and, we’ll see you all next time.
