The first trip, we stayed all day, exhausted ourselves. Now we park hop. Usually doing the EE park first, then hopping to the park that was EE the day before. Like, we'd do MK on Sunday a.m., go back to our hotel for a break, then over to MGM (MGM had EE on Sat.) We usually go in September, so we end our day at Epcot, usually. It's open the latest. We have been known to do Fantasmic and then walk over to Epcot for Illuminations (that is, if Fantasmic is at 8:00 or earlier.) It makes the day so much more enjoyable for us if we park hop. Mixes it up, so to speak. But, everyone has their preference. You'll just have to see what you and your party likes.
