I was looking into it myself, tripadvisor has a lot of reviews about it. Most people seem to like it, though the cruise ship passengers from MoBay were all scared for their lives on the trip there. I heard it is $25/person (whether or not they drink, or their age) and the tour lasts ~30 mins. I believe you get a rum punch and to try 12 different rums (basically drink as much as you want) but not the good stuff, (or the great stuff, or the amazing stuff). I think we are going to pass, mostly because I will be the sober driver and I'm the one who bleeds rum. If you buy bottles there I hear it is just a little cheaper than anywhere else, except duty free.
