This is a GREAT service!!

We used the Car Care Center when we were there in May. My mom and I were attending a conference at the Gaylord, but wanted to stay at the Poly instead (duh, right?) plus we wanted to use Magical Express, so we used Alamo at the Hess station right inside the MK gates. It was fabulous!
I called for a pick up at a time that was convenient and they were right on time. It took all of 5 minutes to get there, my car was ready, and a few minutes later I was back at the Poly! It was great!
Go to alamo's site and use the code ORLR72 for location. I found the rates to be a bit cheaper too since they don't have as many airport fees.
Then when I returned it, I waited outside for a shuttle back to the Poly (but there were people who were waiting to go to a park too, so you can certainly do that as well). Then we were able to use ME to go back to the airport at the end of our trip!

We saved money too since we only needed the car for the few days we were going back and forth to the Gaylord - after that we were at the Poly and used Disney transportation. HTH!
