We do one on our animal kingdom day, like yesterday. We did tusker house at 8, was in line for safari by 9, finished with the park by 1, because no lion king. The bus goes to blizzard beach, we brought our bathing suits in backpack. Spent 3 hours at the beach and went home, ate dinner, watched the movie on the lawn and went to bed at 10.
Up late this morning 8 am, for another beach day if it stays warm. We will go to dtd for lunch at 11, and depending on rain or not, hoping not, we will hit typhoon lagoon after lunch and, at 4:30 we have a BBB appt at dtd then dinner with Cinderella at park fare.
We always do 4 park days, one break day, four park days one break day, two park days and home. We fit in quest, both water parks and one round of mini golf if not more. Water parks and quest usually are no more than three hours for us, but you could stay longer if you like them, we get bored and need to move on. But we do several fun things in one day usually, like golf and blizzard, or quest and typhoon.
Have fun.
