We're in the same place at the same time, 4 adults & 4 kids. Unfortunately they might be a bit young for you, 9, 9, 8&7 - little kids I suppose! I'm sure we'll al have a good time though - there were loads of kids of all ages last year.
We are going 2 Jan staying at the Bor (bit of a walk outside town I hear, but hopefully a cheap taxi ride!). 2 children, girl age 7 boy age 12. Our boy can't wait to go (first time) and will be keen to find friends his own age. May see you there or at Gatwick at 4.30 in the morning!!
