My dad used to drag us into the American Pavillion show at Epcot just so he could nap. But I would have to say hall of presidents, I don't think I have ever stayed awake during that entire show.
For some reason every single time we make it to my TWO favorite attactions....AND I do really love them BOTH I always nod off....Hall of Presidents and Carousel of Progress.
For us, it is definitely Spaceship Earth. We love the ride, but it is so nice just to be able to sit and relax. We also rest on Living with the Land boat ride. NO napping, just resting.
American Adventure. I love it but I take cat naps through it.
Ellen's Universe or Energy. I love it too but cat nap through it.
The ending of Great Move Ride.
