SFO clubhouse

Hi

Does anyone know what time the clubhouse opens in SFO? I am flying from LAS arriving in SFO at 12:40 and then connecting to VS020 for a 16:30 departure so once I collect luggage and check in for the flight to LHR I am hoping we can go straight to the clubhouse.

Thanks

4 hrs before the flight, looks like you'll be fine ...
