Hi, I realise this isn't an AIBU but I couldn't find what I needed on Google so here I am....
This weekend I'm taking the kids to the Victorious Festival in Portsmouth and was wondering if anyone knew roughly how much spending money we'd need?
We're only going on the Sunday and rules are you aren't allowed to take anything other than babyfood (doesn't apply to us) and factory sealed water.
It will be just me and my 9 year old twins (moody teenager is refusing to come!) and everything in the kids arena is included so bouncy castle / rides / facepainting / circus / roller disco etc is all 'free' though I expectthere will be plenty of other stuff they want that will cost me 
How.much typically does food cost at these things?
We're going for a big breakfast beforehand but obviously they will still need feeding later in the day.
