Has it not always been the case that you could take a companion into the F lounge? I do it most weeks at T5. Two guests would be different.
I am also due to receive my renewal pack in the next few day so will review it with interest. While I did make +2500 points last year, I think it was only 2300 the year before.
Instead of Hilton Diamond Elite (is that any good?), I’d rather they did something useful like interline bags!!!!!
