We used them a few years ago when I broke my finger, and couldn't drive the rental car. My wife didn't want to drive back and forth from the airport to L'Esplanade, so we used them instead of airport alternatives like Kenny's. They were fine, easy to deal with (they met us on time at the airport and at L'Esplanade for the ride back) - but either $5 or $10 per day more expensive than the alternatives.
