Any other hotels near or on airports?

Not your warmer clime, but Morey-middleton (C29) just outside of
Middleton, might work, IF you can keep the rates low. There are number
of motels within a few miles, but most seem to be expensive, geared
toward the business traveler. There is lots of business park land right
across from the airport, so possibly one could build there.
Nearby is Madison (You know all this Jay), both a university town and
state capital.
There is a class C airport in Madison, but its usually busy. C29 is
untowered, and under the outer ring of the class C.

Interesting. Madison is a virtual clone of Iowa City, but on a larger
scale.

Pretty danged cold, though. After 40 Wisconsin winters, I'm loathe to
subject myself to that again!
