Dune Buggy Rental

We will be on Royal Caribbean and are looking to rent a dune buggy for the day in cozumel. Where are the vendors and any recommendations?

Shore excursioneer dot com is who I have used three times for dune buggy tours in Cozumel. The first two times we had the same guide, Roger. He was great. We have requested him for our third in 19 days!:D
