I think the amount of time at AK depends on whether or not you want to walk any of the trails to see the animals. When my twins were two (they are 8 now) we spent from 8 am-5 pm at AK and we still missed a lot. We did do the safari, the Lion King show, we walked one of the trails, took the train over to the petting zoo area, and did a few other shows, ate counter service lunch and watched the parade. If we hadn't taken our time to walk the trail or see the parade we could have left by 1 pm or so. We enjoyed the trails though because we saw hippos, monkeys, gorillas... The parade was a highlight for one of my twins too. He just loved the music and the costumes. A lot of people park hop, but I am a type A personality and that is too chaotic for me. We have always picked a park and spent the day at the park. When the twins were little, the best thing for us was to get to the parks at opening and push it until 4-5 pm. Sometimes they would fall asleep in the stroller, sometimes they didn't. They rarely slept at the same time, but that was nice! We got some one-on-one time with the other twin. We would leave the parks and head back to the hotel for a quick swim and usually some take-out for dinner. We never ate table service because our twins were a nightmare to take out. We would get the kids to bed around 7-8 and we would do it again the next day. We missed all the night shows that first trip, but we have made up for it since.
