There must be loads of opportunities for one off functions, business meetings,parties etc.
I think this would be the road to go down to increase usage.
I know someone who tried to book the AR lounge for a party and didn't hear back from the club.
He also tried to book a table for 10 for a Thistle function with no reply. On both occassions he contacted them a number of times.
So a bit of professionalism can only be a good thing.
