I tried the Eco-limo today to get to and from the airport. OMG - LOVED IT! Don't use Super Shuttle anymore, don't drive use these guys! It's a small firm, and VERY responsive. I'm never driving or parking at the airport again!
Don't think you are hopping into a beat up VW van. You are getting into the nicest of nicest prius, with leather seats, dark wood, bottled water. It's like riding in a Lincoln, but in a much "cleaner" car.
