The holiday inn on the lane was right next to the school and the shuttle took me everywhere (school, airport, greyhound, etc). It is a little bit expensive, but I think they might give a discount for interviewees and none of the other hotels I called had shuttle service, so I figured the difference I paid would equal taxi rides, etc.
But, if you go to the osu website for the undergrad school, there is a whole website dedicated to nearby hotels and their numbers...I think somewhere under the visiting the campus.
