We stayed on the south coast in an all inclusive resort, golf course etc etc and it was great. Close enough to hit San Juan too. Definitely do the rainforest walk (er "soak"). But, as with anywhere, there are places you should not venture, night or day. Some aren't obvious so as the concierge or other knowledgeable source. For example, we jinty'd to a horse riding facility on resort and while the rest of the family rode, I decided to walk back to our place through the golf course. They ended up sending out multiple security people to find me. Seems that bandits will come out of the surrounding hills and rob people on the golf course. Won't find that one in the brochures!
