Thanks for both replies. No upgrades - just paid cash for Biz class as it was an OK fare for that time of year.
Is there anything fundamentally downmarket about the Oryx Lounge? We never seem to enjoy Al Mourjan - takes too long to get from one place to another and always crowded when we have been there (between midnight and 3am). From past experience, we will be looking for peace and quiet, soft drinks (preferably freshly squeezed juices), and champagne.
