How strongly is the "12 hour rule" enforced for checking bags and getting boarding passes at the resort? We have a 9:45 p.m. flight home, which means that the earliest we can check our luggage and get our boarding passes would be 9:45 a.m. I would hope to be in the parks by then. Will they let us check in at, say, 8:45 a.m. (13 hours before our flight)?
