We only spent a couple hours in the Animal Kingdom park on my recent visit -- just long enough to accomplish our main goal, a ride on Expedition Everest:
This was an absolutely wonderful ride. It was exciting to be able to finally ride it, after having seen it under construction 2-1/2 years ago.
The ride area has excellent theming; the line "pre-show" area was a curious mixture of real Everest history and mythical Disney lore related to the "Yeti," who "stars" in the ride. (Think the Abominable Snowman at Disneyland's Matterhorn, only much bigger.) I thought the ride might end up being a little too intense for me, but it wasn't at all -- I loved it and can't wait to go on it again one day!
We also had time to fit in Dinosaur, which is a wild jeep ride similar in style to Disneyland's Indiana Jones ride.
