I am taking my niece and nephew (both teenagers) on their first trip to Disney for spring break next month. We plan on visiting the four parks in three days so I intend to double up on one day. We will be visiting Animal Kingdom in the morning (with the intention of getting there early but we are not staying at a resort hotel), and then go to Epcot later in the afternoon with dinner reservations within Epcot. I made all of my FastPass reservations for Animal Kingdom (Primeval Whirl, Expedition Everest, and Kilimanjaro Safaris), but I am now wondering if I should use FastPass instead for Epcot since according to the Unofficial Guide, the parks are more crowded in the afternoon and I am sure that they will want to visit the popular attractions of Test Track, Mission: SPACE, and Spaceship Earth.
Should I switch my reservations to Epcot? Thank you for any recommendations that you can give.
