I do!
It's a beautiful place with beautiful azure water, beautiful guacamole except on the last day where the avacodos weren't exactly ripe and caused some nasty burping as a result, with beautiful people that seem to go out of their way to make you feel tall.
The turtles and barracudas you can see while diving there are amongst the largest you're likely to see providing you are diving in the Mexican Caribbean
The Mayan ruins at Tulum that you would see as a result of a 3/4 vote where Chichen Itza was ruled out (which is okay because Chichen Itza is just too darn fun to say) are really, really cool despite the throngs of people and everything being roped off and oh yeah man was it hot that day. If anyone knows a good book I can read about Mayan ruins and culture please PM me.
Xel-Ha is a sort of meh place with okay snorkeling fish-wise but nothing much going coral-wise but it has some of the nicest hammocks you're likely to sleep the rest of the afternoon in, and the less said about the "swimming with dolphins" there the better.
I recommend travelling there with people who would be inclined to catch a cab to some local places to walk around and not a guy who didn't want to leave a place where the food and drinks were free and a couple of girls who were under the impression that such a trip would instantly lead to yet another dead Canadian.
(Three Canadians have been killed in Mexico in the past while, which is why every time I heard a bang I said: "Uh oh. There goes another Canadian." This actually happened three times.)
It is also a place where vegan travellers might find themselves eating more raw and healthfully out of necessity than they do at home, and no bad thing. I'll just pretend it was all organic until I hear otherwise.
If you ever do go to visit, I know an excellent archeologist chap who used to live there who's full of great tips and suggestions and will very generously help you out.
