I might get flamed for this, especially by those who claim AK is more than animals, but if you come from a city or area with a nice, large, well-kept zoo, AK doesn't have as much to offer, IMO. Yes, you have some really good shows and rides and more hands-on attractions, but the main attraction for me was the safari ride. But, I have a really good local zoo and the allure isn't as much at AK as it is for the other parks.
Edit: I think that may change with Everest though.
