What is your best park strategy???
1. Using the Fast Past System
2. I like to work my way around the park like in a circle, instead of jumping from one attraction to another that is far away.
Which leads to tip #3:
3. Don't wear yourself out! (We actually wore ourselves out on our last trip. It was my fiance's first time out there and I wanted to show him everything I could in 5 days!) Take daily breaks and try to minimize how much you walk. (If that's even possible!

A good tip for that would be to use the train in MK to go from land to land.
4. When I plan my trips, I like to plan my day in MGM Studios about half way thru. My last trip was 5 days, I think we went to MGM on the 3rd day. Reason I do this is because MGM tends to have the most attractions that require sitting for a period of time. It helps give my feet a rest!
What is the best way to avoid the largest crowds??
Use early entry if you are staying on-site. Then you can take your break around noon, when the parks tend to get crowded!
