We allocated 1 day for EPCOT on DD's first trip when she was 2 years old. We were there from open to close and did not feel like we had enough time. She loved EPCOT!!! She is 9 now, and we have been every year since that first trip, and we always spend 2 days at EPCOT. It still is by far her favorite park other than MK. Lots of characters, including Princesses to meet and greet in World Showcase, performers throughout WS, the boat ride in Mexico, Agent P adventures throughout WS; lunch or dinner with the German band at Biergarten, Nemo, Turtle Talk with Crush, Living with the Land, Figment, play areas after some of the rides, aquarium, Spaceship Earth, Club Cool, Innovations, Soarin (if tall enough), Test Track (if tall enough), Mission Space (the green easy side if tall enough); Kid Cot stations and passports to get stamped at every country; Pick-A-Pearl and I'm sure a lot more that I am forgetting
