We booked Prieto Tours for an airport to hotel transfer and hotel to airport. No problems getting to the hotel. Was given a paper for an appointment the following day. Of course, NO ONE showed up. Someone from TravelPlan called the Prieto rep and it was his day off and he said to meet the next day at 1pm. Guess what, he didn't show. We were tired of screwing around and decided to take a taxi back to the airport.
