To answer the head line.. NO. Americans are not as gullible for fads as the japanese are. Nor are they into "cute". So no, the Duffy fad will not be successful in the USA. I much rather the WDC tried to imitate OLC in how to operate their parks, as opposed to mimic fads that are solely a gimmick to make money, as opposed to spending it where it really matters: maintenance and quality.
