What a family day.  We came off of the cruise ship.  For a family of 5 (kids in 20's)...we spent $175 for the day (7 hrs) and never had so much fun with the activities / beach and had more great food and drink than we could handle (including the tequila shots).  Coming off of the ship on Saturday...we agreed it was the highlight of the cruise.  Again, a great balance day...fun and partying.
Note:  The employees were professional and courteous and the facilities were clean.
