Don't be too upset about the resort being built on the beach at Playa Rincon. Not only is the project on indefinate hold, but since the enire Samana Peninsula has been declared "environmentally sensitive," any future projects will have heavy environmental considerations to deal with. You might want to check out the What's New section of
www.samana.net for pictures and the latest information on this project and another, a campground overlooking Playa Rincon.
There is also another development project under construction worth noting, an eco-tourism oriented attraction located on Playa Fronton at the base of the majestic Cape Samana. This project is to become part of the new Cape Samana National Monument. More information and pictures can also be found in What's New on Samana Net.
It's absolutely true that Playa Rincon is as pretty as you describe it and many of those of us that live in the DR would like to see it (and Playa Fronton) stay that way.
