Great tour! Rosalia was an excellent guide; very knowledgeable and super personable. She picked us up at our hotel precisely at the agreed time with a comfortable van. Her English is excellent so no communications problems whatsoever. Her knowledge of Tulum and of Mayan civilization was impressive. She was very patient with my young granddaughters and explained things in a way that they could easily understand. She wisely planned an early start so that we were able to beat the crowds at Tulum. Swimming and snorkeling in the cenote was an amazing experience.
