I was there on 1/12 before my flight to Sydney. Those of us on the Sydney flight had been notified early in the afternoon our flight would be delayed until 12:01am. When I entered the lounge at 4:30pm they attendant told me right away that the lounge would stay open until boarding started. It stayed quiet until about 8:00pm, but even then it wasn't jammed back full. I kept going to look at the dining room and it was never more than 1/2 full. Most people were eating from the buffet (love the tapas) or the appetizers they kept walking around with. I really miss the lit up bar, the white is a little boring to me. That is what linked all the other Polaris lounges together. My seatmate was a first time United Polaris flyer, I asked her if she had checked the lounge out and she had no clue there were lounges. Another couple I met in the Polaris lounge had spent 2 hours in the United Club before they took a walk and stumbled across the Polaris Lounge. They were disappointed the United Club didn't direct them to the Polaris Lounge from the start. I think they need to put on the boarding passes, you are welcome to "blah Blah lounge" for each city in their trip. That would be nice for passengers that don't have knowledge.
