You might want to keep an eye on the DME discussions on the transportation board as you get closer to your trip. In the early days of DME, there were long, very slow moving lines to check in for flights at the resorts. Hopefully things have improved now that the service has been in operation for 3 months. Also, the check-in desks are only staffed during certain hours (7am-2pm? or maybe it's 6am-2pm?) and your DME bus will depart your resort 3 hours prior to your flight, so if your flight leaves earlier than 9am, your DME bus will be picking you up before the resort check-in desk opens for the day, in which case you will have to take your luggage with you on the bus.
