I was told or heard that what was de Lonvilliers was divided up. Some units are now owned, some are rented, and some can be reserved through the Beach Restaurant. If I remember correctly, there's a separate door on the non-beach side of the restaurant for check-in to the rooms.

I have not seen the rooms that can be rented through the Beach Restaurant so can't comment on them. But since the check-in for the rooms is on the back side of the restaurant, it does appear there is some association.

Restaurant is definitely completely finished now and is wonderful.
