We though DME was great. When we arrived we didn't have to wait, we got in line just as the bus pulled up.
When we left, we got there early just cuz we thought about changing before taking off. We had no problem getting to two of our carry ons. We registered with the mears guy and talked to him for alittle bit. He did say that they were trying to set it up so when everyone got to the stop to wait for DME back to the airport, that you would sort your luggage by terminal a and b. They want to put up signs that will end alot of the confusion. We didn't have any problems and would definitely use the service again.
Also, while waiting to go back to the airport, we did see the truck pull up with luggage. The staff quite efficiently pulled the luggage off the truck by room in those metalk cages they have and emptied teh bus rather quickly.
Some thingsto learn about dme though:
--don't expect your luggage to arrive with you. They do bulk deliveries.
--make sure you call the number given to you the day before to make sure they have you scheduled and they are pickingup your luggage from your room (why bring the luggage down and wait in line to check it into the storage area?)
--the airlines that you can check into at the airport, you cannot check in after 2pm...don't even try it...
all in all, i think it is a great service...
