We used Victor in San Juan. We had dubbed it our "mystery tour" because we didn't know what we wanted to do.
He took us to old SJ and new SJ. We hit the outskirts of the financial district. We stopped at a beach where we had an ice cream. We stopped at the fort for a quick look see. He took us through the shopping area. All along the way he was more than informative of PR. He knows his history! We did end up at the fort for a show(only on the first Tuesday of every month). We saw local folklore dancing ..it was nice.
