XPost from BHB: Vacation Rental

My FIL's live in Pittsburgh and are looking to rent a house here for a week before the wedding. Does anyone own or know of a reasonably priced rental property in Suffolk?

The dates would be Sept 4-9, for 4-6 adults. We live in Bohemia and the Wedding is in Moriches so something between or near those towns would be ideal.

TIA
