Hi,
We have driven to Florida from western NY (through Erie, Pa. then down Rt79) a few times now. Not sure of the route you will be taking (RT75?)

... Georgia would be too far for us that first day...
Each state have their own coupon booklets at the tourist info centers as you enter them. We make it as far as Wytheville, Virginia usually the first night and have stayed at the Sleep Inn and the LaQuinta. Also have made it to Charlotte, North Carolina the first night. That is 13 hours of driving for us that first day

. Charlotte has a lot of traffic, so we try to make it to stay on the south side of town and that way miss most of the traffic the next morning.
Hope this helps...
Bonnie
