We are a party of 8 adults who will have already done one day at Universal going from Universal Studios to Islands of Adventure on a park to park ticket. We will have two more days New Years Eve and New Years Day. We are staying off site and have no Express tickets. We will not stay late as we will be there the following day. IOA starts an hour early (unless it changes) on New Years Eve. I had thought about going to IOA first and doing Forbidden Journey and then using the Hogwarts Express to USF and then riding Escape from Gringots but I don't know if Hogsmeade Station will be open at 9:00 to go to USF. Is this possible?
