I have inspected the Diamond Lounges at Caesar's, Flamingo, and Harrah's Las Vegas, although not Paris/Bally's, within the last two months, on multiple visits. The three I visited all have the shorter hours and the hummus/salsa thing going on. Most disappointing. But, as you say, it does cut down on the crowds since no one wants to visit the lounge to eat any more. Older folks (the Harrah's crowd) don't consider chips a meal, and I heard quite a bit of grumbling. To me, the most ridiculous thing is rolling up the sidewalks at 9 (!) PM. They call that Vegas?
