dude its pretty fucking gay we were trying to get one in burlington after a formal and we couldnt without a credit card. you have to be 21 to pay cash. let me know if you figure it out.
All you have to do is have your dad call up there, and say that you're going to arrive before him, and that he would like you to be able to check in so you don't have to wait outside for hours. I have family friends who have done this, and it worked well. They never actually wait for your parents to come.
