I would like advice on which area on the Pacific coast is best for a family with two teenagers? Should we choose Manuel Antonio, the Nicoya Peninsula, the Osa Peninsula, or somewhere else? We want a beautiful and swimmable beach (water not too rough), not touristy, a "local" experience, and a hotel that is a bit more upscale than average. Not an all-inclusive, but good food accessible. Can you also recommend hotels?
