You can do your Rincon research by reading the Coqui. It has a few articles and many listings: restaurants, hotels, Bed 'Breakfasts, Inns, vacation rentals, beach properties for sale, yoga teachers, massage therapist, surf board rentals or surf instructors, in essence, all the businesses or services you'd need for a perfect tropical vacation.
About 5,000 issues are published, but you don't need a hard copy. You can download it off the net. The Coqui website has a pdf version and an event's section listing monthly activities.
The December Coqui is a special edition: It's in full color and about weddings. Everything you need for a perfect wedding is listed: locations, wedding planners, photographers, and stories from couples married in Rincon.
