Can I get a guide on-site if I just show up at Ek Balam? All of the tours I've seen are hilariously expensive if you're just one person by themselves, so I'm thinking about renting a car and driving to the spots by myself.

I know CI won't be a problem for finding a guide, but Ek Balam? Do I even need a guide or is the site still that much of a mystery to everyone?
