Hi i’m Travis and hope this helps. I went to Puerto Rico in 2008 and had a great time. We stayed at the El San Juan hotel and casino,They had a great breakfast buffet,several resturants, clubs,and shopping inside the hotel along with a great pool on the beach. Look at my pictures.I would suggest non diving ideas are the ruins and just walking around taking in the amazing sites. Also go to El Yunque rain forest is awesome and the waterfall is nice.Both the historic districts of Ponce and old san juan are nice to see. As for diving i would suggest you go with Sea Adventures in Fajardo, they will take you to Sebastian and Lobos dive sites which are really nice. With wonderful aquatic life.Look at my Forum post for more info about the dive itself. i hope this helps and you will have a wonderful time. i do suggest the bioluminescent bay which we missed out on unfortunately.
