I actually disagree completely. Having "rides for the whole family" means having more thrill rides. There are a ton of rides and things for little ones, there aren't for older folks, teens etc. And while you might think the classic rides like small world "Hold up" I'd say you are wrong, and I'd say the thin slice of crowd (usually because nothing else is available) that go to it, also demonstrate this.
I know a whole bunch of families who are "aging out" of Disney, because there isn't enough there their teenage kids want to do, they think a lot of the rides at WDW are lame, and they want more exciting thrill rides. You can also see Universal keep eating into WDW's market share, that also says a lot about who is really succeeding at attracting people. Heck, look at Pandora and how successful FoP is, a massive thrill ride, and it has certainly generated unseen hype for WDW compared to the last few years, including FL2's opening.
