Had a free transfer through Lomas travel through United Vacations. We usually use another transfer service and was unsure at first as we had a bad experience with a different service in the past. Our plane was late and there was a long line at immigration, but they had a private shuttle ready for us in under 5 minutes! We had to go see one of their reps the next day at our hotel to schedule our return. We met with him, and it only took minutes! Our return driver was on time, and we even rode back in a Lincoln Navigator, and it was only supposed to be a van! That was a very nice surprise! I would definitely use them again!
