I wish there was a way that Walt Disney World guests could go through a training session of sorts where they are introduced to common crowd issues, the procedures Disney puts in place to help control them and make sure people are safe, and how to be patient or completely avoid any issues to insure a great vacation.
So many folks think rules don't apply to them or they have a certain exception to would allow them to do what they want to do. This goes for the folks cutting in line at the bus stop. It goes for the people who stand where they aren't supposed during a parade. It goes for the people who take flash pictures in the attractions.
People are visiting the most popular vacation destination in the world with so many different people from different walks of life. Yet, I wish there is some way to make people understand that that a bus can only hold so many people and another one will be there soon. No worries. Or that you can't show up to the first showing of Fantasmic 10 mins before it starts and expect to get in let alone a seat. There may be a second show. No worries. Or that you just can't stop in the middle of a row in a theater that is expected to be full. Your experience will still be great. No worries.
Walking in a theme park all day with young children, playing loads of money on admission, food, and souvenirs will drain everyone's energy and patience, but in order for EVERYONE to have a good time with less stress, EVERYONE needs to cooperate, otherwise, situations like these occur and people's vacations are ruined.
