I am doing that next week. I have a ride from the airport to the resort but need to take DME back. I called CRO and made the one-way arrangements with them. You can also call DME directly and give them your return flight information. You will receive information at your resort the day before your departure concerning when you bring your luggage down and what time the bus will pick you up. The CM I spoke to said that the info would be placed on my door, but I have read that it has been placed UNDER the door. He also said that the average pick-up time is 2 hours and 45 minutes prior to your flight.
