AC is still safe.
But Diamond Lounges in Vegas have been decimated (for the last few months); they also cut back on hours.
Just got back from AC, and the AC lounges still have decent hours and all of the food as previous.
Problem, was that the lines were incredible. I was there 3 nights, and didn't go once.
Solution (thank goodness), is that Harrah's
has finally coded me as LFB; so I had unlimited food (with limitations) and beverage for the weekend. I would have gone to the lounge out of convenience, but I refuse to wait to get in. And, it's personally nicer to just sit at one of the bars (such as the sapphire bar) and relax having drinks; added plus is that the selection of premiums is better.
