I love St. Martin but I love PR as well. It doesn't surprise me that it's ranked #1 as it has so much to offer between Old San Juan and it's cobble stone streets and forts (most Caribbean islands have nothing even close to this, including SXM) as well as a rain forest, a beautiful coastline and offshore islands including Vieques. San Juan also has some amazing restaurants and great nightlife. Anyway, I know this is a SXM forum, but I when I saw the negative comments about Puerto Rico, I had to give my two cents!
