For any who might be concerned, all 3 Delta Queen steamboats are safe. All were upriver from New Orleans, or on a different river altogether. Delta Queen's offices (and reservationists, according to what I read) were moved to upstate NY, where the HQ of Delta Queen's parent company are. Good news in an otherwise terrible situation.
Didn't want to "walk on" the previous poster's question about MSC Cruises, but I did want to get this informationout. Please anyone with info about MSC Opera transatlantic, go to the main heading (Other Cruise Lines) and check out his questions.
