We had a layover in Miami and had about an hour to kill. We got to the lounge a little after 9 on a Friday. It was super crowded but most Centurion lounges seem to be nowadays. I guess that's why they're getting rid of that card benefit - too many people have the Platinum card nowadays and the lounge isn't really exclusive anymore. Miraculously, we got in within 5 minutes. Finding a table was a different story but we were able to find two seats in the outer room, which I didn't mind because it was away from the dining area, so it was much quieter.
Despite the crowds, staff was still able to keep the buffet tables stocked and clean. We had some potatoes, pancakes, scrambled eggs (typical continental breakfast powdered eggs) and some fresh fruit, which there was a good variety of.
I probably won't be back since 1. I don't know when I'll be in Miami next 2. They're getting rid of the benefit in March 2023. But it sure beats waiting at the gate!
