Hearsay stories are hard to read about. We don't have all the details and there are a lot more questions than answers.
Counterproductive, in my opinion.

As far as Club mobay, for just an hour, I'd wait because I like the arrivals services. If you aren't a person who likes the other benefits of CMB arrivals, then just wait outside. For $100, you can buy a lot at the restaurant! More than an hour, I'd forego the whole thing and hit the road!
