Actually the tour at Bacardi is no charge. If you are the type who likes to ventrue on your own then you can get there for around $5.00 per person.
My husband and I took the
Ferry across the water way to Catano. Cost .50/pp each way. The ferry ride is approximately 10-15 minutes. Once there we caught a taxi for $2.00/pp to the Rum Factory. The Rum Factory tour can take a couple of hours, depending on how long you stay there, it is a self directed tour with a telephone and headset type thing to direct you around. You also will be given 2 tickets for free rum drinks when you arrive. After the tour, there are Taxi's waiting there, again $2.00/pp back to the ferry terminal and $.50/pp to return to San Juan.
Was one of the best self tours we have taken, of course we are advernturesome and do try things on our own. We actually had a local waitress from Sr. Frogs tell us how to take the tour.
The ships tour is by bus and is usually around $30.00 per person to get the tour.
