If you're interested in dating, I wouldn't suggest it. But, then again, it depends on what you're looking for.
There are many "players" on the island and if you're okay with a limited relationship, you'll fit in just fine. Just keep in mind, that with all the tourists that come onto the island, the shopping list changes almost daily. There is an unlimited supply of good looking, fun tourists that are under the premise, "what happens in San Pedro, stays in San Pedro". However, the shopping list for the locals pretty much stays the same. Whatever, you're looking for, just play it safe.
