I am looking for info on the front of line feature at Universal. Before our annual wdw vacation next May we would like to stay one night at a Universal hotel to take advantage of the Front of the line feature at I of O. QUESTION- Do you have to check inn first to take advantge of the front of line or do we stay the night then check out of hotel too use the front of line feature?? Remember we are just staying one night. Can we go to parks before we check into hotel or the next day after we check out of Hotel???? THANKS...
