I've been talking to ZMan67S and gave him these links.
Check this link, stay away from the Inns in Stillwater unless you have money to spend.. With the exception of Comfort Inn. Most of those Inns are bed and breakfast types.
I'll open up my house as well to anyone, I live about 8 miles from the fair grounds. I have 1 bedroom with a queen bed and a finished basement, so if you have air mattresses etc you could stay down there also. If there is enough interest I figured I would have a BBQ/get together at my house.
