American Cruise Lines is offering three uniquely themed, eight-day river cruises to celebrate the holiday season. “A Southern Christmas,” which departs Dec. 21, will travel the line’s Historic South and Golden Isles route from Jacksonville, Fla., to Charleston, S.C. Along with onboard activities including ornament-making and caroling, in-port excursions include a visit to Charleston’s beloved Holiday Festival of Lights and an oyster roast on the beach at Georgia’s Sapelo Island. The small ship will be decked in traditional Southern holiday décor, including magnolia leaves and citrus fruit. “A Cajun Christmas,” which also departs Dec. 21, is a round-trip journey up the Mississippi River from New Orleans. Highlights include an onboard réveillon-style feast — a long meal replete with regional dishes (think gumbo and escargot). Also, you’ll have an opportunity to experience the Louisiana Christmas Eve tradition known as Festival of Bonfires: a sparkling of large, wooden structures set ablaze to light the way for Santa Claus. Departing Dec. 28 on both of the aforementioned routes (though in reverse for the Historic South route), American Cruise Lines’ “Old Fashioned New Year’s Eve” rings in 2014 with a New Year’s Eve cocktail hour, dinner and champagne toast. Depending on the ship, you may be treated to fireworks over Savannah, Ga., or to a holiday tour of the Houmas House Plantation and Gardens, known as the Crown Jewel of Louisiana’s River Road. From $3,750 to $4,195; rates include all meals, beverages, entertainment and personalized service.
