Interesting... I'm getting a different message for a room at the Pop Century. There's no mention of the $25 fee. Here's what it says under the Rules & Restrictions:
One important difference between booking on Orbitz and booking with Disney, however, is that Orbitz collected the cost for my entire stay in full when I reserved the room. Disney takes a partial deposit at the time of booking... at least in my experience.
You may have found the one Disney resort that Orbitz did not add the $25 fee to. I checked about 7-8 Disney resorts, all categories, and they all had the $25 change/cancel fee. The fee is the major reason I stopped booking with Orbitz, last year.
