Our kids, 4 and 2, have been loving epcot because of the playgrounds they have setup. I think there are three different playgrounds and we grab a couple of snacks and a drink and let them run around. There is a monsters inc, radiator springs, and just a plain backyard playground. There are a few seats for the adults to relax in as well. I wish they had the playgrounds during food and wine so the kids would have something to do while we sampled food.
Oh, and there is a Phineas and Ferb topiary which our kids loved.
