I don’t know if they have limousines, but we used Shuttle Express to provide van service between the parking lot and the ceremony site for our wedding (the wedding was at Seahurst Park, it was over a mile walk otherwise with a fairly steep hill, and we had some mobility-impaired folks). They were punctual, professional, and polite.
I don’t recall what they cost because my husband set things up with them, but I seem to recollect that it wasn’t unreasonable.
