It was a hoot.
I am not a big fan or expert on cruises having been on two others Holland America and Norwegian, trust me friends this is neither. It is a 50 year old reproduction of a 1890-1910 river cruise ship. The rooms are tiny, the bath/toilet with a marine toilet that you have to pump to flush is out of the past, the average age of the passengers is 77 and there were one pair of newlyweds who were 95 and 98 respectively. The entertainment is corn-ball and local and the shore tours are on yellow limousines AKA school buses. The food is nothing overly fancy, but substantial and tasty enough that I gained 5 lb and my wife 3.
We both enjoyed it immensely, it is fun, laid back, low key, you tie up at night so you can sleep like a babe. Do not go if you want to gamble, drink to excess, stay up all night partying or try to impress your shipmates. But the scenery particularly in the 1000 Island area is outstanding, the crew from captain to cabin attendants/waitresses were friendly, kind, and personable. My only reservation is that once you get through the 1000 Island area the river widens considerably and the scenery is less interesting. I would recommend the slightly shorter trip through the island area and back to Kingston and then take the train to Montreal and Quebec City if you really want to go all the way down river.
