Just wanted to throw this out there....in March, we used a company called Magic Transportation.
www.magictransportation.com
They were recommended on this board, and I can't say enough good things about them. It was $80 Round trip from MCO to All Star Sports, and included tolls, tax, 2 child car seats, a grocery run and they gave us a stroller to use during our stay.
They were waiting for us when we arrived, with our last name on a sign. The airline lost one piece of our luggage so we were at the airport longer than expected, and our driver was nicer than can be.
When we finally got to the van, he had a giant Mickey Mouse doll in one of the child seats. Talk about starting the magic right away!! My kids were soooo excited! He then gave my daughter a Disney autograph book and a pen, and he gave each of the kids one of those glow in the dark ice cubes.
We also used them for a trip to and from Sea World, and each time they were punctual and courteous. It was the same driver each time.
I would absolutely use them again!!
