There is one in Middleton, MA, but unless you are using the room for a conventional rendezvous I would pass.  The local LE seems to have it out for the ladies as I know of at least two who were pinched.

If you're still looking suggestions e-mail me at [email protected] and I can tell you about some places that offer day rates.

I have a room I'm not using-LOL.  

Good luck, Kate
