Since there didn't seem to be any current postings on Diamond Lounges, decided to see how crowded they were. Stopped by on a Thursday at Flamingo, Harrahs and Caesars from 4:30 to 7:00. There were no lines for entry. Flamingo and Harrahs were about 2/3 full. Caesars wasn't even 1/2 full. Food was about the same at all three. Caesars had the most comfortable seating.
