Yup. I've seen that. I used to spend two weeks each Christmas roaming around the Yuchatan. Here is an interesting site if you make it back down there:
Coba It hasn't been cleared out yet. Very interesting site and somewhat off the tourist trail. Also, the El Bocadito is a reasonable place to stay. It was a Club Med when I was there last time.
I've been meaning to get back down there. I'd like to visit Palenque and Tikal when I do. Thanks for the link to the Coba site. I'll look it over.
Coba a favorite of mine. But did the Bocadito finally take over the VA aka Club Med? They were a k apart...
