I agree, get the quote in writing. He did try to raise the rate, but was willing to honor what he'd quoted me. I used him because there was no other viable way to get to the beach...I don't do credit cards and thus can't rent a car. He didn't have a limo available for the trip to, but sent a driver in a van. It was fine with us because what we wanted was transportation to and from the beach.
If you're just going to and from the airport, there is a lot more available. HoJos hooked us up with Jag transportation. They had a huge, roomy van. They offered door-to-door service, unlike cabs...and they charged the same as the cabs.
I'd say, if you need a ride somewhere that you can't get to easily, Tony is fine. For transportation from the airport, try Jag!
