Lots of people still use transportation other than DME. If you want personal attention, if you want privacy, if you feel a secret thrill at seeing your name on a driver's placard, if you really want to make a grcoery stop, then hiring a towncar is your best bet.
I loved using DME. I used it last May when it was only 4 days old, and I'm using it again this November. Believe it or not, taking a towncar is no guarantee of getting to your resort quicker. It MIGHT be quicker, but it's possible it could even take longer than DME.
Here was my experience, and remember this was back when DME was brand new. From the time I got in line at the DME Welcome Center until the time we were dropped off at CBR was 53 minutes. I timed it because people on another message board were waiting for me to report back, since no one had yet used DME before me (I had the phone number of a fellow poster, who bravely agreed to trust me with her actual home phone number so that I could call her and she could post real-time info to the rest of the folks). I couldn't time it from landing to resort, since we made multiple stops in the airport.
Anyway, 53 minutes. Let's compare that with towncar service. The ride from MCO to most resorts is about 30 minutes no matter how you go. That leaves 23 minutes in play. I spent 23 minutes waiting in line, checking in at the counter, waiting for the bus, and then waiting on the bus until it left. If I took a towncar, I'd have had to wait at baggage claim for my luggage to arrive, gotten my luggage, waited for the driver to load the luggage and also waited for the driver to bring the car around to us, dispense with any quick paperwork, etc. Well, let's say you spend 10 minutes waiting at baggage claim. You COULD wait a lot longer, but best-case scenario is 10 minutes. Let's say it takes 5 minutes for the driver to get the car, get back to you, load the car, get you situated in the car, and leave. In all reality, that all probably takes a little more than 5 minutes, but again, let's call it a best-case scenario. In a best-case scenario, then, it's my 23 minutes versus your 15 minutes. It took me 8 minutes longer. EIGHT MINUTES.
Personally, I like spending 8 minutes more and $120 less, but that's just me. And remember, if baggage claim takes you 5 more minutes than my estimate, and waiting on the driver takes 5 more minutes than my estimate, then I got to the resort quicker than you.
I forgot to add that you can also get a grocery delivery to your resort. If you choose to make a grocery stop with a towncar, I can't imagine THAT would be quicker than using DME. Grcoery stops are usually 30 minutes.
