My bet is they won't have it open 24 hours. They'll open it without the amenities 1-4, then close it. Then open with amenities and staff it from like 7am until sometime in the evening and close it, put all the stock away, and open it again as a waiting room at 1. That is all speculative.
On another note, I hope they use some of LAUS's classic big leather(ette)chairs in the new lounge. They should have at least a few of the ones they took out of the old ticketing wing when they closed it around someplace.
