We went to DL last summer for the first time and had a blast, so of course we're returning this summer! Last year we printed our tickets online and they exchanged them at the gate. I'm wondering if we order 4-day Park Hoppers in advance, is there anything special about the actual tickets we'd receive? Are they cool souvenir plastic tickets (like credit cards) or are they just paper? If they're cool, I'll order those; otherwise we'll just print at home again. Also, how far in advance can we make Priority Seating reservations for Blue Bayou? Lastly, how many days prior to our arrival at DLH should I call to request a specific tower? Thanks so much for all your help! This board is SO helpful -- I love it!
