It's a difficult situation, but maybe one that is the result of your DD having always had what she wanted without too much fuss from you and your DH. Perhaps she has become accustomed to being able to make her plans in the safe knowledge that you'll always be there for her - as you have up till now.
I do completely understand your upset, and in particular how frustrated your DH must have felt at being put in such an awkward position with his golf club. Your DD obviously didn't consider these consequences when she cancelled, as all she was trying to do was rescue an important date in her calendar the best way she could. She probably felt that you and her father wouldn't be remotely interested in a night on the tiles and a party at theirs into the early hours (I know we wouldn't!, so the obvious solution would be that you have the GC - after all, you've never minded before.
You were absolutely right to make your point, but maybe now is the time to get in touch and tell her that you will, of course, have the children (with a gentle reminder to ask in future). Please don't let the situation get out of hand. In the meantime
for you.
