The American Queen Steamboat Company, whose steamboats roams the Mississippi, Ohio, Tennessee and other American rivers, is offering a special for those who book by Dec. 31. Book early, pay-in-full and save up to $600 per stateroom ($300 per person) on any of its 2014 American Queen or American Empress voyages 7 days or longer. It's website said the offer is valid only through Dec. 21 when I visited, but if you click on the "view details" link, you'll see that the deadline is actually Dec. 31. For example, a 9-day trip from St. Louis to Minneapolis, July 15-23, in an outside stateroom with a veranda (category C) costs $4,099 per person; the sale price is $3,899. In both cases, a $109 port charge is additional. I traveled on the American Queen steamboat in the Upper Mississippi and enjoyed the trip tremendously. Read about it here.
