Love AK! It, and EPCOT, are our 2 favs.
When we go in the fall it's only open from 9-5, typically, so we usually stay all day.
Love to ride Safari first thing in the a.m. and then last ride of the day.
For us DHS is a 1/2 day park, at most. Now that we have ToT in DCA we can skip it there (I know it's different, but I like DCA's better) and last time we rode RnR it was so painful (ear-wise) that we didn't even use of FP for another turn)
MK-if we didn't have DLR in our backyard MK would probably be our favorite park, but that's another park that we can do a 1/2 day in.
There's really only 2 things I don't like about AK..
1. It can be really hot there

2. Jungle Jammin' Parade-due to the parade route you get blocked from riding Safari until after 5. When the park closes at 5 you can't reach it from the entrance (believe me, we've tried-only to see the entrance less than 20 feet away with no way to get there)
Last trip my DD11 and I decided after starting the day at DHS and then going to EPCOT (where my DM71 left us and went back to POP) we would rush back over to AK (Evening EMH to 8) to so how many times we could ride EE. We got to our car in the DHS parking lot at about 7, drove over to AK, parked as close as possible, quick walked through the park (stopping for a PP pix on the bridge) and rode EE 3 times in less than 8 minutes! IT WAS AWESOME! She still talks about it.
