So we have a had a change in plans now that Universal upgraded my tickets to the buy 2 get 3 free day ticket. Will be staying a night earlier than planned at an offsite hotel. It is my understanding that the day I am to check in at PB I can go to the hotel early in the morning, check in and park my car, then get my tickets and express pass and then go to the park and return around 4 to actually check in to the room. Is this correct? Was not sure considering the room key is the express pass and that morning I would technically not have a room at this time. Just wondering how this all works.
