We took our daughter when she was about 15 months back in October 2001. First we wanted to make sure she would not be afraid of the characters in the park. We bought VHS Tapes of two specific Sing-A-Long Song videos.
Disneyland Fun and Beach Party at Walt Disney World. In these videos the large characters interact with all the kids all over the parks. She would watch those videos over and over leading up to our trip. When we got there she couldn't have been more excited to see all the characters. No fear whatsoever. Easy to do and really helped her to be excited about going to Disney.
Rides and Experiences:
MK- She really liked Small World, Dumbo, Pooh, Peter Pan, Buzz, Aladdin.. She loved spinning in the teacups. We must have rode the carousel 10 times too! She did HM and Pirates. Didn't like the drop in the dark but dealt with it fine. Just kept reassuring her that it was all fun and she was fine during scary parts. Loved the parades and the fireworks too! She liked going to "Mickey's House" in toontown to meet Mickey. She loved the train ride as well.
Epcot - She liked Spaceship Earth, Universe of Energy, Journey into Imagination, and Living Seas.. She liked the interactive stuff in Innoventions. Anything with a computer mouse was hers! She liked the boat ride in Mexico and enjoyed dinner there as well.
MGM - Did not like the Great Movie ride. Very scared. Didn't like the gunshots. Loved Playhouse Disney. Loved Beauty and the Beast Show. Loved 50's Primetime Cafe. She enjoyed all the antics going on there.
AK - Loved the Lion King Show and the Safari Ride. Loved the Dino Boneyard where the kids can dig for fossils. Was scared in the Its Tough to Be A Bug Movie. Should have kept her off that. Felt bad we brought her on.
Baby Swap was huge for us. DW and I got to ride all the big rides while one waited with daughter for the other one to come out.
Sleeping was an issue.. We were all in small room at ASMO and she did not like the pack and play crib. Ended up taking rental minivan and driving her to sleep pretty much every night. She just was so excited. Glad we had decided to rent that car!
She is now almost 3 and loves to watch the videotape from our trip to WDW. She asks me at least once a week if we can go to Disney World again so even though she was so young it defintely impacted her.
