Those are my pictures and they were taken at off times.
The lounge did fill up quickly for breakfast. We would arrive right at opening, at 7 am and the tables for seating were filled within 10 mintues. I am guessing that many people, like us, were getting breakfast at that time so they could get to the early park opening. I'm not sure what the lounge was like later in the morning.
The only time we were there for evening appetizers was on a rainy afternoon and it was indeed a mob-scene in there. Food was cleared out quickly, but it was also replenished fairly rapidly. We didn't find that the other guests were rude in the lounge while we were getting our plates. We took food back to our room to eat.
