We have used the Fairfield Inn in Macon a couple of times. Easy to get to and good free breakfast. Macon is south of Atlanta, I'm sorry I can't remember how far, but we have done it several times. (Doesn't seem that far)
I second the McDonough exit 221 area. Hapeville & Sullivan Rd. are both right at the airport & IMO not very nice areas.......McDonough is only a few miles south of there & a much better area.
