AK has always been a half day park for us. There are many very good attractions (Dinosaur, Everest, numerous animal exhibits, Festival of the Lion King, Finding Nemo) but on a normal day you can do all in 1/2 day there. Since our last visit they have added Avatar and also River of Light night time show to hold the crowd longer and extend the operating hours there. Perhaps our next time there will be a full day or perhaps just the second half of the day instead of our usual opening the park approach.
