My absolute must dos: take the monorail to Epcot - not the bus, Spaceship Earth, Soarin, Three Caballeros ride in Mexico, Beer in Germany, Wine in Italy, The American Adventure (both singing pre-show and watch show), watch Candy lady in Japan, eat dinner at either France or Canada.
Likes, but not must dos: Turtle Talk with Crush, Imaningation Ride (with Figment), Test Track, dinner in Italy, Norway ride, French movie, get a pastry at French Pastry shop (behind restaurant), taking the boat to the boardwalk and walking around for awhile.
Would not recommend: the higher end version of mission space - had a headache all day after I did that!! Wine tasting in France - going on 3 years of not so good wine, eating in Norway - definitely an "interesting" slection of foods.
