BTW Club Lounge now open 24/7. Cocktails from 5:30-7:30pm. No limit as far as I could tell. Free-Wifi in the lounge and I believe the club rooms include free wired high speed LAN.
May be worth having breakfast downstairs in Espresso on the Mezzanine one day if you can at no extra charge. Espresso's buffet is a bit more robust than the lounge's.
