I would devote an entire day to AK. I think you will feel really rushed otherwise at that park and any other one you try to go to. I would also pay attention to the park maps there. They have walking trails to see animals that Mike and I completely missed last time because we were trying to hit all the highlights and get to MGM. I have heard fabulous things about the Nemo musical so I'd definetly try to see it.

Oh and we did Kali during december a few years ago and it wasn't all that bad. We wore ponchos because I wanted to go on it so badly.
