Could someone recommend a catamaran company they've used in the past, to sail from Cancun to Isla Mujeres for the day? Just 2 of us, so likely has to be a public/group tour instead of a private charter. I looked at several catamaran websites; can't really tell which one is better. I searched the Isla forums but the hits were either out of date or for private charters. Would prefer an outfit that would give us a few hours free time so we can rent a golf cart and go around the island. Thanks in advance for your info.
