If it weren’t worth keeping around for the profits then we know it would be shuttered, so it is making enough profit somehow. I’d say about half the time I pop in just to people watch and enjoy the music for a little bit the floor is actually decently full.
Atlantic Dance will almost certainly outlast this new place. I’m betting it doesn’t last 5 years unless they revise their pricing downwards within the first two years.
I've heard for years that there's a deal in place with Swolphin which requires Disney to operate a nightclub on property, which is why it's there (still).
If profits were the only parameter, Mannequins would still be there.
