We'll be arriving with some friends the first weekend of November. We've been on a Sunset Catamaran cruise before as part of a wedding reception. We'd like to do it again with our friends. Any suggestions on who we should book with? Or, should we book now, or will we be able to do that when we arrive? Would like the cruise that lasts 3 or 4 hours with food and drinks included. Also, would like to watch the cliff divers at Rick's? Please advise.
