We have been several times and have learned the following:
1. Get an early start and eat your main meal at lunch. This gives everyone a break. Then, when most people are eating their main meal in the evening, the lines to the rides are much shorter.
2. If there are two back-to-back showings of something, like the Parades, plan on the second, you will not have to get there as early or wait as long because the gap between the two showing are short.
3. Be prepared and know that virtually every major ride exits into the gift shop.
It is a great place to visit. Have a good time.
