We will be at the parks for three days. We are planning on MK, Epcot, and trying to decide between AK and Hollywood Studios. It is my husband and myself and our three college age kids. Three in the group have already been to all four. Suggestions which the majority of us will prefer. We are going the week of Christmas. I know . . . very crowded. Is is possible to do these two in one day this time of year? That is what we did last time when the kids were young. ANIMAL KINGDOM OR HOLLYWOOD STUDIOS if we have to choose? Thank you.
