Go on Goodguys web site and they list all the local hotels and their locations. There is a map of the area. There is also links to the hotels which show you their facilities. All the info you need is there.
As said earlier, the Crown Plaza host hotel is sold out way in advance. The host hotel is really nice to go to because they have stuff going on all weekend. There are other hotels near it though. You should look at the Interstate 71 and Dublin Granville RD. interchange for others. There are also some hotels a few interchanges south from the host hotel. I don't know your transportation status but downtown Columbus is also a good place to stay. There are restaurants and bars on High street all over. Downtown is also very close to the fairgrounds where the show is held. It is pretty easy to get around Columbus in my opinion, but anywhere around the show can be a little crazy that weekend. If you have any questions let me know, I lived in Columbus for 10 years.
Tonner, you will be OK there. It is dead nuts downtown Columbus. Not much going on down there on the weekend. Not a lot of restaurant options.
Easton Town Center is a great place, Dublin, Worthington, Gahanna, all good and safe locations. Don't let the mileage fool you, the fairgrounds are easy to get to and everything is easy to get to.
