We were in Cancun last February. For the first time, we went to Isla Mujeras for an afternoon and had a great time. We did the golf cart thing and drove around the island. We are going back in May and this time, we want to spend a day at a beach that has a bar with food. A guy was pushing one of these at our resort but we were unsure if we were being overcharged so we did not do it. Once on the island, we saw a few beaches that looked nice but now want to rely other travelor's recommendations on which beach with this set-up one is best. Any help will be appreciated.
