Our experience with Sergio excellent gude and Javier very safe, efficient driver was exceptional! The air conditioned van was fabulous, and since it was just the guide, the driver, my husband and I, we learned a lot and had a great interactive experience. The lunch was delicious at the buffet between monuments! The only down side was, due to the sargasso problem in the sea currently, a swim at Tulum was not a fun option, so we instead chose a cold drink, and a cool ride back to our hotel pool. Highly recommend!
