When I stayed (the month it opened) the Lounge was decent. But I may have been one of the few guests to use it since it sounds like it quickly was closed. I had a fantastic stay in July 2019 -- back when it was a steal at 8,000 points per night (plus I got the new property bonus of 500 points a night).
