I'll throw my two cents in as well...
From day one i have been incredibly impressed with the design of this park. It is one of the most beautiful theme parks, zoos, whatever you want to call it, in the world. In addition, it is so well planned out, with the various pathways, lands, etc. There is so much potential for growth, which will not make the park seem awkward a la Disney-MGM Studios. That being said, when it first opened I still felt the park was a half day and I took my time. On my first two trips, I left the park by 2 to 3 pm. I didn't miss anything except the parade. At this point Asia and Kali had opened. Granted I also arrived when the park opened at 8. (Back then it used to open at 8) I guess we could have wandered around the park the remainder of the afternoon but there was little point. We had already circled the park, been to the stores, and seen somethings twice. But even then i still thought it was a lovely park and as some of you have said it is very relaxing.
But on a recent visit to Sea World I realized how much better AK could be. Sea World thoroughly impressed me. Although people complain about the rides at AK, both my best friend and I agree that the main problem is lack of animals and contact with the animals. AT Sea World I felt surrounded by animal exhibits, shows, etc. all day. You also have a lot of close contact. Please don't mention Rafiki's planet watch as most of that place, other than the clinic, is a glorified petting zoo. In addition, the three rides at SW just felt like an added bonus. You just don't feel that at AK. And if disney is going to emphasize that AK is not a zoo, then they need to add more attractions. You also feel an enormous waste of space at AK. For example, Camp M&M? Yes FoLK is there but that's it. There are no animals, no rides, nada! No adult is going to sit through Pocahontas.
Hopefully with Everest the park is headed in the right direction. But Disney also caused itself alot of bad press by opening the park without Asia. I still know tons of people who skip AK based on what they were told the first year it opened. Guests really did demand their money back and complained about the full price of admission back when it opened. But I have hope that the attractions will catch up with the beauty of the park.
