It gives a crowd rating from 1-10 (1 being least crowded, 10 being most) and color rating (green-least crowded, yellow-medium, red-most) for each park on each date, plus the holidays and events going on that day that may peak crowds. The refurbishments (attractions that will be closed during that period of time) will also be listed.
What character dining experiences are you planning on doing? Would love to hear more about your plans!
As for the rides that are "musts", it really depends on the kids, but since you are traveling with young kids, some of the attractions I would recommend are:
In Magic Kingdom: The Many Adventures of Winnie the Pooh, the new Fantasyland expansion, it's a small world, Dumbo, Aladdin's Flying Carpets, Peter Pan's Flight, and Buzz Lightyear's Space Ranger Spin
Hollywood Studios: Voyage of The Little Mermaid; Toy Story Mania!; Muppet*Vision 3-D; Beauty and the Beast
Animal Kingdom: Kilimanjaro Safari, Triceratops Spin, Finding Nemo: The Musical, Festival of the Lion King
Epcot: The Seas with Nemo and Friends, Turtle Talk with Crush
Good luck!
Animal Kingdom: I definitely agree with Kilimanjaro Safari and Festival of the Lion King! Also, since they are younger they might like the dinosaur dig thing too!
Magic Kingdom: Mickey's Philharmonic (I think is what it's called) would be cool for them too....we've wanted to go on Peter Pan's flight, but the wait is normally long, so we went for Mickey instead, and it was so fun!
Epcot: Definitely Finding Nemo for them! I will say, too, that we saw a really cool gymnastics show in China there, and it was neat to watch!
I probably missed it, but where are you staying? Animal Kingdom was fun with all of the animals, but any of the value ones would be awesome too!
Not for the 1-yr old, but the 5 and 6 yo should definitely do Soarin. If they meet the height requirement (my 3 yo brother did) then you have to do it. They have a baby this where you can get an extra fast pass. So your 5/6 yo will get to ride twice and each of you guys get to ride once! It's a great system. Don't skip on that ride.
