We booked with Tiffanys Towncar Service. It will be cheaper for us than using Mears. We also will take advantage of grocery stop on the way in from the airport.
We used FL Tours, and they were great. They also provide a free grocery stop. They have a coupon if you book online. We'll be using them again our next trip.
Yes I am also interested in getting more information and advice on towncars. I have finally narrowed it down after reading ALL (and I mean all) the boards and discussions on towncars.
We are traveling in mid June to MCO, and I have called many companies and the rates are fairly close. I guess it comes down to service.
We also used FL Tours when we went to WDW in January. Everything was perfect, our driver (I think his name was Sonny) was waiting for us in baggage claim. We still made a grocery stop even though our flight was 30 minutes late. I used the internet coupon with no problem. Pick-up was right on time and car was very clean and nice. I also like that they are a sponser on the Transportation board here!
