Oryx Lounge

[Soph]

I have a 7 hour stop over in Doha on my way back from Bangkok, so thought I would try out the Oryx lounge as somewhere to while away the boring hours.

I have been online to find the info out, but cant see any info on how to actually book a place, as on their website it says you have to book 24 hours in advance, but of course I wont be there 24 hours in advance!

Has anyone used this service, and if so, what is the best way to book and pay for it - and can I not just do it on arrival?

Thanks in advance. K
