Only did the cenote - Our bus tour had this as a stop for lunch. We did a brief, but too long for me, welcome with a Shaman. I live in an area with 50/50 indigenous/ non-indigenous people. The photo ops and ceremony felt awkward for me. At the same time I respect they want to demonstrate their culture. My suggestion would be absolutely have a welcome that is authentic but then provide people an opportunity to learn or explore more about the culture by inviting those interested. The cenote and the change rooms/ facilities were amazing. Lockers included in the price of the life jacket rental. Whoever designed it did a great job. Stairs down were slightly terrifying, but they were sturdy and a few platforms so you could let people by. I am afraid of heights, but it was well worth going down for. I went barefoot and I think a non-slip footwear would have been a better choice. We were amazed by how many people did not plan ahead for the cenote. Bring a plastic bag for wet swimsuits and towels. Many only wore a swimsuit with clothes overtop and then were traveling in wet clothes for the remaining 8 hours! Had I known there was the opportunity for a culture tour I would have preferred it and skipped the Catholic church, as learning more about Mayan culture is important. This is something I will suggest to the tour company.
