Had been on previous trip with American Cruise Line and had a wonderful time, appreciated the intimacy and friendliness of small ships. The staff were all exceptionally cheerful and friendly. There was an on-board historian who provided illustrated history themed talks about the Mississippi River, its importance during the Civil War, its contemporary commerce, and its natural history, that were hugely informative and entertaining. The shore excursions were fun and fascinating. Learned a lot on this trip. The food was amazing, varied and sophisticated and delicious. Most of shipmates were retirees, generally seemed to be people in their 60's through perhaps 80's. Most were well educated and had interesting career histories, all were gracious, most were good conversationalists. But plenty of privacy was available also if one happened to be in the mood. There were plenty of choices, one could do activities with groups, or go ashore and do one's own thing. Lots of fun.
