This sounds nice. Disney has never had a problem making pretty locations. What set Pleasure Island apart for me, was the very live entertainment available. Especially the Adventurers Club. I know that a recreation of that same club is unrealistic, but to have venues that are as alive and immersive as that would be what puts this over the top.
I know I'm clutching at straws, but I see no reason that the Adventurers Club and the Comedy Warehouse could not be part of Disney Springs. OK the "wacky" theme of the AC probably doesn't fit with the upmarket-retail-and-dining-experience but the whole place seems to be a themed environment anyway, so what's it matter that they offer a little light hearted improv in the evening?
