Currently in the Al Safwa lounge now (13:00 on a Friday) and theres a total of 5 other people in here. A little different to when i was in here last week on a Sunday night/Monday morning. There were around 20 people in on the Sunday night but i managed to get a sleep room straight away. In the morning around 06:30 there were well over 50 people in the lounge with the majority if seating near the water fountain filled and the private cabin things opposite the toilets pretty full too.
FYI to enter i just went straight to the Al Safwa reception desk without visiting the Al Mourjan. They asked if i wanted a room straight away on both occasions.
