I'm a disney pro, but a newbie to universal. A couple of questions. I see the hotel rooms say they sleep 5 adults. We are 2 adults and 3 kids (the youngest is a very petite 4 year old) and when I try to plug in a price I keep getting an additional 50.00 charge for him. Is there any way to avoid this charge? We don't need any extra beds. He's a teeny pipsqueak And how does 'check out' work. Like disney, if we're paid in full can we just pack up & leave, or do we have to go to the lobby & check out? TIA!
