BarCar you're not on Tatnell or Parbury by any chance? If so I know the very marquee and party you are referring to!

But lucky us, we got a note shoved through our door on that same day warning us that this would happen. I was trying to work out whether I think this is unacceptable or not - at first I thought a big party once in a blue moon is fine, but as my husband pointed out, if everyone did that then no-one would ever get any sleep! Also, they had a similar party about a year ago, and got tons of complaints, which is why I think they tried the note thing...
