Some of you are making an interesting point, one I wonder if Disney has contemplated (I'd assume they have, but who knows?)
Sure, maybe Adventurer's Club and Comedy Warehouse aren't money makers in and of themselves. When Pleasure Island was an entire area you had to pay one price to get into (much like the theme parks themselves), as long as attendance wasn't slacking in AC or CW, you could argue that they were popular, people were visiting them, they should stay. The reason certain other types of clubs were replaced was because attendance was down at those clubs; you could argue that enough people weren't interested.
Now, you have a situation where PI is going away, so attendance in and of itself becomes a moot point. CW & AC have to make revenue commisserate to the amount of money it takes to keep everything running, wait staff and entertainment and crew, etc.
But have AC and CW ever been measured as "loss-leaders" since PI changed admission procedures?
Are there people going to DTD, specifically or primarily to go to those clubs? And do surrounding Disney-owned ventures benefit from that? Are there stores that see more business because of a proximity to AC or CW? And perhaps more to the point, if either or both of those parks were moved somewhere else, would they help bring busines to nearby ventures wherever they are?
I just think of the old adage "Where there's a will, there's a way." Here are 2 entities that have a decent degree of popularity. Disney hasn't figured out to make money off of them yet. Instead of trying to figure out HOW they could make money off of them, they decided to not bother.
One thing I never thought I'd say of Disney is that they'd give up on trying to figure out how something they created, that's popular, that draws fans and tribute web pages and merchandise, could make them money.
And it's that sort of thinking that makes me suspect that the closing of AC & CW is a decision made from some high-up-muckety-muck's heart and not head. Someone who's not too keen on AC, decided it's not worth even trying to save it, or make it a dinner theater/cabaret on its own with a cover and/or minimum. I dunno, just seems short-sighted to me.
