We took my oldest DD to WDW when she was 3. The were planning to do all 4 parks in 3 days.
Big mistake!
The park we could have easily skipped was DHS. She was afraid of the Little Mermaid Show, we kept missing the Playhouse Disney thing, and she had a meltdown before we could do the Muppets or the HISTK playground.
She did however, love Epcot. She did Soarin' once, liked the Seas Pavillion, and the Journey into Imgaination ride. We spent a fantastic afternoon wandering the World Showcase. She liked the Kidcot craft stations, got to meet the following characters with no waiting:
France: Belle and Beast, Aurora
Morocco: Jasmine, Aladdin, and Genie
China: Mulan
We also ate dinner at the San Angel Inn in Mexico. DH took her on the boat ride in the Mexican pavillion over and over while we waited for our food.
I've got 3!!!!
2 primary school DD's and a toddler DS!
