Can I serve vodka at kids parties?

Not to the children.... obviously.... unless they are Very Annoying.
I now have an 8 year old girl and a 6 year old boy.
Tomorrow, my boy Cole is having a Gladiator party at the local sports centre.
We rather enthusiastically invited many friends assuming some couldn't come - but they are All Coming.
And I am a tad concerned that "Gladiator Party" sounds a bit more exciting than it actually is. Scott Hall sports centre, last time I was there, was in possession of at least 4 triangle shaped foam objects, a tired looking spring board, a few grubby balls and a stroppy teenager referee....
I have told Cole that Wolf or Trojan or Cobra probably won't be there.... I am hoping to manipulate their six year old minds with the offer of sweets, marshmallows, crisps and some weird sour snake things....

I genuinely big-time, seriously love hanging out with my six year old boy. It's certainly more interesting than a lot of grown ups. Cole is a deep-thinker - and no I'm not biased.
He laughs really really loud at all of my jokes, which proves his high intelligence. He has excellent manners - after burping he can follow it with burping the words "excuse me".
Cole's "friend" Percully - you know, the type of friend no-one else can see/hear/speak to - sadly died whilst bass jumping on top of a mosque. Let that be a lesson to you all.
