Hubby has a conference that overlaps with our currently booked vacation. The conference precedes our vacation. I can’t decide if me and the kids will stay with him on our arrival night or just get to our hotel and settle in. Until we decide, can all of us be on two separate hotel reservations on the same dates? What about when it comes time to making fast passes? And what happens once we finally decide and drop one of them for the overlapping nights? Thanks!
