Open bar was amazing. The thirty minute ride felt longer. I was able to finish three drinks but next time I plan to get four to get my money's worth. Look for deAls, go in the evening, check out living social, go during the weekday but at the end it's so worth it. It's one of a kind. The tourist crowd is a lot of fun. It's expensive enough to get a good of crowd of people. I plan to do this again and again and again. Open bar is the only way to go for sure.
