We were directed to wait til the bus was ready -- about 5 mins. There were only 2 or 3 other people on the bus with us -- about 8:30 p.m. during the off season.
Make sure you have your DME voucher out, the CM at the podium will scan your voucher, ask if you checked your luggage, and assign you a bus lane. You don't have to tell them you came in on an earlier flight if it is the same day as your check in to your resort and you don't have to go to the counter..
