Timely post indeed!
Just back from a couple of days myself in Tehran with Accor – went for the opening ceremony for the airside ibis/Novotel, which will fully open in October.
I found the ‘CIP’ lounge useful both ways, for the points you mention. I flew with EK from DXB (another option – 4x flights a day, and less than 2 hrs from DXB) and was told CIP is complimentary for premium pax or $85 otherwise.
Interesting observation about the ties – yes, I stuck out in the ballroom!
