Last week my entire family used DME with mixed results. Four arrivals, four different stories. On Sunday, August 28th: My sister and her family arrived at MCO at 8:50 AM and were at BWV by 9:00. My DD and her boyfriend arrived at MCO 11:40 AM and got to BWV at 1:00 PM. SO and I arrived at MCO 1:05 PM (we missed the earlier flight with my sister, don't ask) and were in our room at BWV (DD checked us in with my CC so we just had to pick up our keys at the front desk) by 2:00 PM. On Wednesday 8/31, Mom arrived at MCO at 9:10 AM and got to BWV at 11:00 AM.
Overall, I would say the arrivals went very well. Mom wasn't happy that she sat on an empty bus, that stayed empty for 50 mins, but all in all, not too bad.
We all departed together. Our flight was at 8:35 PM and they scheduled us on a 5:20 PM bus. Were at MCO by 6:15. Much too early in my opinion. Most major airports are no longer requiring you to arrive 2 hours prior to your flight, and the hotel had already checked us in and printed our boarding passes that morning. I would have preferred a bus at 6:30 or so and to have had dinner on property rather than eating at the airport. While the airport is huge and there are many options for eating, the better restaurants do not allow luggage carts, which was a problem for this group of 8 who wound up eating in the food court...blegh.
Overall our opinion is we would use the service again. Not having to deal with the luggage and having the hotel check us in for our flights were great conveniences.
