We stayed at Gettysburg CG three years ago with a TT, so we took the truck sightseeing. Had such a good time, we are going back this August with our Class C. We reserved a minivan from Enterprise because we don't tow. They apparently do pick you up! They'll also drop you off afterward if you make arrangements.
We're also taking a motorcoach tour to Washington, D.C., for the day. You can pick it up at Gettysburg CG through http://www.daytontours.com/dayton.html. We may also take the minivan to Hershey Park.
Hope you have a great trip!
