My frontal lobe agrees with you, but my instinct answered Everest. Such different rides they're impossible to compare. AK doesn't have a huge quantity of rides but the quality is excellent
Expedition Everest is my favorite Disney ride anywhere. Flight of Passage is a very strong 2nd at AK. In my opinion, it's hard to classify the safari as a ride. Yes, you're riding in a moving vehicle, but the experience is more of an exhibition or even a show to me. Either way, the safari is always a must do for my family. No visit is ever the same.
expedition everest is my favorite modern ride, and favorite roller coaster. (due to nostalgia i cant compare it to HM, POC, SW etc)
but i havent been to avatar so i almost didnt vote since i might skew the numbers.
EE is ride #1. I do enjoy FoP a lot... enough to be willing to wait unusually lengthy times twice on my last trip to get in, but I just cant categorize it as a ride as I would EE. I see it more as a visually enhanced experience. You dont go anywhere except in your mind.
I chose Kilimanjaro Safari as my top choice, but in all fairness, the last time I was there Avatar Land wasn't open yet, so my answer could conceivably change once I experience it.
I think FoP is the best ride, one of the best experiences Disney has every created - it is just so convincing about the conceit of the ride. So I voted that.
But my personal favorite among DAK rides is Everest.
Wow, this is a tough one. I guess I underestimated the number of good rides at AK. When you see the list you realize how great that park is. My gut instinct was to go with Everest, but I love Kilimanjaro, FoP and Dinosaur. I voted FoP for what it's worth.
