On our way from Wisconsin to Florida Chattanooga is a good place to stay for the night.
The Best Western at Kimball Crossing turned out to be a very convenient location to stop.
It's easy on & off the interstate, gas is right there, and there are several restaurant choices within easy walking distance. The motel itself was clean and quiet, the two things that are most important to us. It's not handy to downtown sites, obviously, but we were only 20 minutes from Lookout Mountain and the Chickamauga battlefield site, which we visited the next morning.
