We were considering the Park Hopper just to get into and out of Animal Kingdom and Hollywood Studios to check out a couple of things. I didn't see us spending entire days at either with a limited schedule, but figured we might ID a couple of things we REALLY wanted to hit at each and just check them out when we had some downtime (i.e., after coming back from MK for an afternoon nap or something).You can leave and re-enter the same park on one day without Park Hopper, right? So, if we spend the morning at MK, then want to go back to the hotel for a bit, then re-enter MK in the afternoon, that's doable with a hand stamp or something, right?
