Oh, I should add that if you buy APs online, they don't get activated until you're ready to enter the park the first time, so generally you have to go to Guest Relations to activate the AP before you enter the gate the first time. So don't wait until the first morning...if at all possible, activate your AP the day before you actually need to get into the park. We had a mid-day arrival on a Saturday in mid-December, and I thought we allowed plenty of time to activate the APs and make our FP+s times by arriving an hour before the FP window started. Yeah, that didn't work out for me. The Guest Relations line outside the park was over an HOUR. I was so angry.
