Civil War cruises

They're here. I'm picturing seven nights of drunken arguments but the brochure is more upbeat:
Guests can relive the drama of the Civil War era aboard the Delta Queen as recognized experts highlight major battle sites along the breathtaking Ohio and Cumberland Rivers cruise route, regaling the courage, struggle and historical significance of the war that united and shaped the country. Guest performers in the evening will delight passengers with Civil War era music or a surprise visit from Abraham Lincoln himself.
