It is possible to be in the park from opening to closing. The trick is to be prepared. This means taking time to rest and get “away” from it all.
Here are some hints:
-Table Service Dining This gives you a chance to cool down and rehydrate away from the crowds
-Long sit down ride/attractions This gets you off your feet (think Carousel of Progress, Indiana Jones, Nemo, and Universe of Energy- just to name a few)
-Find an out of the way place to sit and relax I love to just people watch while I am there
-Walk around and just notice the little things Like the windows on Main Street at Magic Kingdom, the different animals on the Tree of Life, just to mention a few) Relax and enjoy you are on vacation!
Enjoy your day in the parks!!
