What has changed is that it used to open at park opening, but no fast pass until 11:00 when World Showcase opens. That made the standby very tolerable. Now FP is available along with all Future World attractions. Certainly makes it more difficult to standby.
Agree with Micca that the singalong is very entertaining at DHS. Fortunately, we caught this a few years back, and it is a must do for 2 adult visitors.
