Before we started renting a car for each WDW trip, we used Florida Town Car and were always satisfied with their service. When requested, the driver would make a quick stop to pick up some snacks/drinks for the room.
We always enjoyed using them, especially after Mears forgot to pick us up and almost made us miss our flight. If I remember correctly, Florida Town Car is comprised of a group of independent drivers. In the early-mid nineties, it was very difficult for them to compete with Mears. I believe there was some sort of lawsuit over it, the specifics of which escape me. I think it was because of the monopoly Mears had over airport transportation, as they ran the taxis, shuttles, vans and buses! Anyway, I'm glad to see that their business has flourished.
