Our kids loved Epcot! One thing to do is visit the Kidcot station in each country (there will be a sign). They get a signed postcard with a saying written in that language (I think France was "Bonjour", in Japan and Chinese it was written in the characters.) They got stickers and a little plastic ziplock suitcase to keep their postcards in. They really loved exploring too. Most countries (all?) have characters to meet, entertainment of some sort, some have rides, snacks to try, etc. Future World of course also has rides and characters, and imagination play areas. Epcot was also the least crowded park we visited, so it was nice and we felt like we could take our time visiting without being rushed.
