Hi Robin!
Last year my family drove to Disney. We stopped off at DVC Hilton Head for a few days first to kind of break up the 16 hour drive. On the way back home, I thought we should stop about half way which was Charlotte, NC. We stayed at a Residence Inn but I know there are lots of other hotels on I-77 coming back toward Ohio. We paid $99 for a 2 bedroom suite with breakfast the next day. If you are interested, here's the pertinent hotel info I have from my notes:
5816 Westpark Drive, Charlotte, NC 28217. The local phone number is (704) 527-8110; the toll free number is 800-331-3131. Check in 3:00 pm and Check out is 12:00 pm. Would need to cancel 4:00 pm day of arrival to avoid charge. Complimentary continental buffet breakfast. The price is $99 plus tax for the night. The hotel is located off I-77 and Tyvola Road.
I hope this helps you out! The only thing I would do different, is probably try to get a little bit closer to home. It was a long, long, long 8 hour drive back to Cleveland.
