the booze cruise is done by Steve and its $55 a person. Its most of the day. You go out to Isla mujeres for a lot of fun, snorkel on the way out and party the whole time. Its open bar(included in the fee) and a must if you are at TTR. Especially with Steve.. he is a great guy. any questions, pm me and I can fill you in. we are coming back this year in June again...we looked at other places and even Cabo but just cant stay away.
