The old line associated with Disney was the Big Red Boat, but Disney did not buy that cruise line, they built theirs from scratch. And they never had a casino on board for a couple of reasons. At the time, Disney owned the California Angels and the Mighty Ducks, and therefore could not own a casino. Also, Disney never thought too much of gambling (too bad for them) and look at either buying or building a casino in LV and decided against it.
