Viator, Today in Mérida I went on a Viator tour of Uxmal & the Chocolate Museum. Our guide was Diego, perhaps a long-time guide, but in view totally unacceptable. He asked no questions, and said almost nothing in the one-hour trip to Uxmal. I sat in the front seat, asked a few questions & got only a one-sentence reply. At the site he said little more than was seen on signs. Also the tour was advertised as covering admission charges, but we personally paid entry fees of Uxmal & another site we visited (Kabah?). My wife & I previously used guides many times & the guides were usually very good— but not this time!
