We stayed at Grand Beach in November 2000 in a 3 Bedroom unit. At that time is was an Embassy branded property through RCI, Sunterra reps checked us in and I believe some units were II as well. I don't know what phase we stayed in; the exteriors and construction all appeared to be similar. The building we were in appeared to be all 3 Bedroom, non-lockout units. I may have done a report at the time. I recall it was a low-key place with a few activities geared to young kids. I believe there was a bus trip to a day-cruise casino and a few other adult-themed, off-property things.
Does not answer your question, but I would consider staying here again in a 3 Bedroom.
