Bought the Groupon for $25 admission to the Sunset Champagne Cruise, and it was well worth it. There were only about a dozen guests aboard (probably because it was a random Wednesday in early March), so it was basically a private trip on the huge catamaran. Our crew of Joe, Guillermo, and Captain Adam did an excellent job and went out of there way to get us drinks, take pictures, and point out sights. We each got a free glass of champagne, as well as complimentary soda and water, and beer and wine were available for $3. Parking costs about $6 in the garage for the mall on the marina, and I don't think there was anywhere free nearby. All in all, and excellent deal and a great way for couples, families, or friends to spend an evening.
