We're supposed to vacate our Grayton Beach rental on Friday a.m. but now want to stay until Sunday a.m. Rivard doesn't do two-day rentals. The house we're in is rented already. Looking for: house to rent for two days, there are five of us, three are children beach side of 30 short walk to beach. (I am an OCD neat freak -- no messes guaranteed) under or around 400$
