I guess I don't understand the thinking that AK is a half day park or that you can do the whole thing in 4 hours.
First of all, there is no way you can do the "whole thing" in 4 hours. You can do the major attractions in 4 hours, but you could probably say that about every Disney park. You can just as well say you go to MK and do SM, HM, Space M, and BTM and call it a day.
I guess I don't go to Disney to get through it as fast as I can. The magic of Disney is in the details. If I just wanted big rides, I'd trek on over to Cedar Point -- it's a lot closer and cheaper. I run through life too often -- when I am at Disney, I want to take my time and enjoy the magic.
At AK, you can do KS, KRR, ITTBaB, and Dinosaur in no time and move on. Or you can also do the Maharaji Trail (?), which in its way is better than KS. Or stop and see the gorilla's on the exploration trail or watch the monkeys by KRR. And the Legend of the Lion King is, imho, one of the best, if not the best shows that Disney has. And people rant about the Tarzan Rocks show and it really is pretty good. It's awesome when Tarzan is swinging around the stage holding on to the cloth -- which you miss if you leave after the first 3 minutes. And instead of rushing past the Tree of Life on the way to see ITTBaB, you can take your time and see the awesome "carvings" that make up the tree. And the parade is very cool, as are all Disney parades.

Or you can try to fit all 4 parks in one day. Heck, add Blizzard Beach and Downtown Disney to that schedule too. You will certainly get to experience the magic of the transportation system. And it really doesn't matter to me as I will not be with you anyway. :hammer:
