There is a way to guarantee (but call to verify) a room in the 100 or 200 building if that's your desire. Request an ocean front, either a studio with loft or 1 BR with loft, as these room types are only in those two buildings and only on the 3rd floor. The only downside would be they may upgrade you somewhere else if those units are full, although there are 10 studios and 4 one BRs to rent.

GCBC is a great place to stay and Grand Case is a wonderful town to dine. In six days I'll be sipping Ti Punches there.
