Just curious Keef, but have you always flown in the UK or other country that disallows instrument approaches OCTA?
My experience has been that arriving at a busy-ish OCTA aerodrome in bad Wx then stacking ourselves in the hold to wait in turn for an approach is one of the best ways to ensure we don't all try to use the same bit of air at the same time. I've also been given holds by ATC often enough. Less so with radar CTA than procedural CTA.
