Tips for party hosting

[C1nders]

So I’ve 33 13/14 years olds coming over in 3 weeks. Got 3 large reception rooms plus garden. Doing a basic buffet plus obviously soft drinks. Nice group of well behaved kids. One room is disco, one is chilling, one is food/chilling. Table tennis.

got various fairy lights, candles for chill room, music system , disco lights

my main question is how to supervise? A friend and I are going to be in the kitchen tucked away but there.

Wow.
I mean Why ?

That is an age that are not going to want Mum and Dad hanging about, but you will not want alcohol consumed.
Why would you invite 33 of them ? ......and then throw in fire ??

To be honest I don’t see it as a big deal.
