Actually, the tour company I used, cozumel-tours.com, package was much more than just dune buggies; it was snorkeling, dune buggies, tour of a light house a stop at a croc sactuary, and an agave farm (hope you get Joaquim the tour guide there - crazy man!) - and if we hadn't been running tight on time, a stop for lunch.
Our boat docked and we took a taxi to the Money Bar (you will want to take a taxi, it's too far to walk and I think they charged the two of us $8), which the tour is run out of. Our guide, Santiago, was super, very knowlegable and lots of fun, and I would highly recommend asking for him if at all possible.
As it was such a small group, my friend and I had our own dune buggy, We followed Santiago in the lead dune buggy up the undeveloped side of Cozumel. Just gorgeous - very rocky with crashing waves.
After our big adventure(s), we followed Santiago back to the dock, so we literally had dune buggy curb service.
My friend and I both agreed that this tour will be remembered as one of the days ever. I couldn't recommend this tour and Santiago more highly!
