Disney’s Animal Kingdom is a popular choice for the first park of the daySome people are surprised when there is no availability showing at Disney’s Animal Kingdom on a “normal” day. I believe that I know why. The park often opens first of the four. That makes it the perfect first stop for Park Hopping, especially if you want to attempt the Four Park Challenge. I’m sure that the popularity of Avatar Flight of Passage has something to do with the spots filling up as well.
