Went to Puerto Rico with my wife and two other couples this last week and man did we have a blast! We spent the first night in Old San Juan, and then from there we drove to the western side of the island to a town called Rincon where we stayed in a beach house. It had a full kitchen, a huge deck and the house was on the beach and about 20 feet from the ocean.
Puerto Rico was beautiful and the weather was perfect (mid 80's). The water was so nice we could swim in the ocean at midnight. We did kayaking, boogie boarding, swimming, horse riding, and of course a lot of drinking and eating.

Pretty cool sunset picture, really neat looking cemetary inside El Morro
I have a bunch more pictures on my facebook page.
