Humanity is often over rated.
(Travel Tip: I have never been to Puerto Rico, so I had to call someone who had. I know, for example, that San Juan is the oldest city under the US flag and that the Spanish repulsed Francis Drake sometime in the 16th century. So apparently there is more than one old fort you might want to see. However, my friend recommended Catano, which is across the bay from San Juan. There you'll find a Bacardi run plant that offers free tours and rum cocktails. And there's Punta Salinas Beach. He also recommended Aleli by the Sea, a relatively inexpensive guest house in San Juan, which is walking distance from the major hotels, casinos and restaurants. The rooms are air conditioned, they have a sun deck on the beach and guests are free to use the kitchen and living room. There is also maid service--I asked.)
