Other Middle East and Africa Frequent Flyer Programs - Anyone used beds at RJ lounge at Amman?

I arrive in Amman at 11.30pm and have a 7am flight to Beirut.

I am a one world sapphire so have lounge access.

I have 2 options.
Stay at the Golden Tulip Amman Airport Hotel but the reviews on tripadvisor concludes that I really shouldn't.

Stay at the RJ Lounge Beds but have read reviews on airlinequality.com of stories of being denied entry and refusal to let 2 people into a room.

Has anyone used the beds at RJ Lounge at Amman airport?

Is there a way you can book ahead?

Some discussion here (http://www.flyertalk.com/forum/other-middle-east-africa-frequent-flyer-programs/858995-new-rj-lounge-opens-amman.html) about the lounge, beds and access.
