imho, everyone should really try DME at least once - we find it so much more convenient & relaxing than car rental at MCO. we dislike the chaos at luggage carousels, having to push/pull suitcases thru throngs of pp, long waits on car rental lines, and loading luggage in the exhaust filled garage, the still having to drive to resort, unload, and park. our arrival DME waits have never been more than a few minutes, the ride is pleasant, and we arrive feeling ready to
we used to rent at MCO, and found incoming and outgoing time from start to finish comparable, but DME much more enjoyable.
we still rent a car, mostly at the dolphin alamo/national - p/u & d/o is incredibly quick (excluding time spent chatting with the wonderful agents there

some ppl really dislike DME, but i think you should try it at least once - we were really surprised that we like it as much as we do
