Here's what I can do.
The guest room has a Queen bed as well as a full futon. Also a 55-inch plasma with FIOS. I can give you that room for $600/night, and you can find someone to take the futon and split it with you. Two-person max to the room, though, unless one is under 18 and (preferably) related to you. I don't need the FBI getting involved.
The home office with Queen air mattress I can give you for $350/night. No TV there, but I won't charge extra for wifi.
Downstairs, living room, same TV as upstairs, large sectional sofa. I can give you the longer half the sectional for $300/night, the shorter half for $250/night.
Den, 30-inch TV, regular sofa where the ends recline. I can give you either end for $100/night, or you can have it to yourself for $150.
