SDF, 4th Street Live and all the other cool bars and resturants around. Slugger factory right up the street. I think a vast majority of airlines stay at the same hotel downtown along the river.
GNV, BTV to add make up my top three.
9E is plagued though of putting us at decent hotels but in the middle of an office park or only a gas station and a subway around. If you’re will to Uber you can find something in any city at least.
