We are going to do the Dolphin Swim on Isla Mujeres. We are going to do the 1st one of the day so we can enjoy the island. We are hoping to be able to "bar hop" on the island by golf cart. Can we stop at a local market and buy beer and drink and drive? Also is there a map of good places to stop available anywhere? We are from small town Iowa and our Sunday Funday's include driving around to new dive bars. I'm open to all information! Thanks!!
