Hi Marla,
Couldn't find a toll free #, but here's the Orlando Airport #: (407)825-7825.
We were going to use L&M, but decided to go with a Town Car service.
If you haven't done so already, you might want to do a search on L&M here on the Trans. Board.
Lately, the posts I recall about L&M have been mostly positive. There has been some negative ones in the past though.
The big thing that comes to mind about them is how they push the Insurance Coverage.
Just need to be sure you have a copy of your policy to be safe.
