Good thing for you to just drive. American roads aren't as complicated as the U.K. road system. A standard atlas should do just fine. Renting a car would be a very cheap route for you. Trains and busses are going to be more expensive, plus you may not be able to find one with a simple route to Sandusky. Let us know when you are closer to the time you are ready to go. There are plenty of folks here that would be more than willing to give you some direction as to where to stay, drive...etc.
