There are two sections of chairs for OBBR guests. First section is immediately as you decend the stairs from the resort. Then there are chairs set up by Mr Busby's from the The Great House to the end of Mr Busby's restaurant. Another group of OBBR chairs follows. A OBBR sign is on beach so you'll know.
There is also a nice little breakfast/lunch restaurant at the end of the pier across from Mr Busby's and past Canoa's. Serves good food in a wonderful setting looking at the boats in the marina. Can't remember it's name at moment.
