Unlike others, I think the Bacardi Rum Tour was a waste of time and money. Yes, you do get a couple of free drinks at the end, but all 4 of us thought the tour was boring and sterile. It gives you alot of information, but the presentation by the staff was dull and uninteresting. It reminded us of the tour we did at the chocolate factory in Hershey, which was equally dry and boring.
We've done other rum tours, like the Mont Gay distillery in Barbados that was much more interesting and less regimented.
Just my opinion on that one.
But I do agree with others that the rain forest and El Morro are a couple of interesting places to see.
