You only quoted a small portion (up top) of my post. My point is, if their cruise line can do it successfully and not offend "little Billy's" parents, in fact they LOVE IT, then certainly the resorts can do it. What is your defense with that? Respectfully asking of course, in line with the discussion .
I'm not defending Disney's position, merely pointing out that it's a reality that won't change, IMO. The cruise line can do it because, like I said, it's in line with an industry norm. The competitive nature of the cruise industry means that Disney has to align itself with what the other big boys are doing. They don't have to do this at WDW, they call the shots.
They also know how to get people to return. They've determined that having adult only areas on the ships is a selling point. They've likewise determined that having adults only areas at the resorts is not a selling point (or else they'd have them in place already).
Of course some people would welcome such a change, some would not like it. Disney is not in the business of instituting polarizing rules. They want to say "No" as little as possible.
Yes, certainly the resorts "can" do it. But they won't. Disney's core constituency is the urban, median income family. Family being the key word. They are simply not going to make operating decisions that favors their non-core customers at the expense of their core customers. They WANT the whole family in the hot tub. That's my point.
