A couple of guides took us to Isla Mujeres on a Hobie Cat for the day. Did some snorkeling on a reef on the way. Trip was suppose to include dinner at the island but there were so many flies we lost our appetite. The sail back to Cancun was a real thrill. The guide warned us before the wind picked up to hold on and a minute later we were flying. We found them on the beach and cost if I remember was about $75.
