I went to Disney World in June about 7 years ago, it was about when Animal Kingdom opened for the first time. I was fortunate enough to get to go to each of the parks, including Animal Kingdom twice since it was my birthday and I got to choose whcih park we went to, but I can just remember it being such and awesome place with all the theming and cleanliness. All the parks are just absolutely amazing.
All the parks have great rides, great food, great shows, great theming, and just an overall great atmosphere.
And yes Nemo I can also see how Star Tours could scare a five year old. Star Tours is a really well done Motion simulator. I actually hated Body Wars, just the whole thing, getting a slinter out of someones heart and the motion made me sick.
But anyways I'd love to go back and ride all the new rides, especially Expedition Everest.
I believe that ride is called Kali River Rapids.
