Should be a fun trip.
Oceanside bones are nomadic for the most part so you'll encounter them where/when you encounter them. There are some that appear to be resident, for instance the ones at Club Med, but other beaches I frequented multiple times had different fish dropping by.
The best advice I can give you is to fish sandy corners near coral heads perpendicular to shore on the incoming tide.
When I go back I am going to concentrate on the south end of the island, flats.
