Perhaps I'm in the "I'm drinking my money worth crowd", but if Sheraton put a monetary value to lounge access, then doesn't that automatically put people in the mindset to ensure they get their money worth?
Having said that, I also think if the ambience and service are not up to people's expectations, it'll just encourage people to eat/drink their money worth.
I'm not entirely sure why Sheraton is doing this. Is it a test to see if investing on a proper bar/lounge is worth it?
P.S. You'll never find me in a G-string, let alone the "G-string riding 2 inches above the pants line" crowd.
