Id go to Epcot! Thats where we are going on Saturday. Crowds dont seem as bad there since its so big and spread out. You can have a great day in Epcot since there is so much more to do than stand in lines for rides and attractions! By the time you get to Epcot, maybe Future World wont be so crowded and eveyrone will have moved on to World Showcase. Hit as much as possible in FW. The kids will like Figment, and the cool fountains. A great way to get of your hopefully not swollen feet is to see Ellen's Energy Adventure! Its a nice 45 minute ride!! You can spend time in the countries letting the kids make their masks at the kidcot stations and seeing the Holidays Around the World. Thats where each country's 'Santa' comes out and tells a story about how they celebrate the holidays. This will be on your times schedule that you get with your maps. Catch the tree lighting ceremony too. What a perfect start to a perfect vacation!!
