7. Long Lines
One of the symptoms of big crowds is long lines. However, long lines can also happen during low-crowd seasons when not all ride cars are in use or other unusual things come up. This is irritating because waiting in long queues means less time spent having fun.
How to fix it: Visiting during slow season will help you avoid most long lines. For the rest, be sure to use the FastPass+ system, consider returning later if a wait time seems too long, and visit popular attractions very early or very late in the day.
