DME was awesome. We were almost straight onto the bus when arriving at the check in, took maybe 40 mins to CSR and then our bags arrived in room 2 hrs later.
For anyone wanting to hire a car, the next day we took transportation to one of the theme parks, then a bus from there to the swan - they have an alamo desk. No line to wait in like the airport and the car was brought right around by the valet. Day before we left we dropped it off with the valet at the airport - excellent!
This meant we did not have to do the drive to and from the airport, which we have done many times before, was great for our driver - DH who did not have to drive immediately after getting off a transatlantic flight this year.
