from the Orlando airport to your hotel or maybe from your hotel to some place else.
If so, there are lots of choices available for you to utilize while you are down there such as Transtar, Mears, Tiffany, Happy Limo, and I believe Coach USA is still around, etc.
Their prices/services vary (for instance I have heard that Tiffany Towncar includes a half hour grocery stop enroute from airport to hotel) so I don't know which one would give you the better deal for your specific needs.
I have only used Transtar so I don't have any others to compare them with. I used only their shuttle bus most recently last year in getting from the airport to my hotel at $80 round trip and service was great so I would reccommend them.
Hopefully, others who are reading can give some feedback about the other companies that they have used in the past to help you make a decision....(bumping this up)
