It was definitely worth going. We told the guide beforehand that our family couldn't swim, so the guide arranged for staff to take us out to sea to see the sea turtles. We did see many sea turtles, but unfortunately, the water wasn't clear enough, so it was hard to see them distinctly. The Nohoch Nah Chich cenote was also very much worth visiting; the water was incredibly clear, but also incredibly cold. A guide took us swimming inside and provided explanations, and we saw many bats that don't suck blood. The buffet lunch wasn't very good. The Tulum Mayan archaeological site was relatively boring; the children couldn't stand the heat and weren't interested in looking closely.
