I asked that this be added to trip advisor. I have been going to KW for years and avoided these for no good reason. Finally broke down and took one. What fun it was! Our driver Mike was great. We enjoyed him and the ride so much. The cost was $1.5 a minute for up to 3 passengers, but I don't think he charged us that much. Pretty small island so can't get too expensive unless your doing a tour. Don't avoid this like I did. Our driver was great and the trip was fun. Learned a bit of fun facts during the trip. They also know quite a bit about excursions..etc. If they just went to the airport, life would be perfect! :o)
In one of the forums someone thought that they may be a bit of scammers but I did not find that at all. They are regulated by the city of Key West and any kind of subversive activity could cause them to lose their permit so they just hold all their drivers accountable. I hope if you give them a try, you will have the same positive results we did.
