I have nothing against you coming, as long as you pay for yourselves!
Tell Jim there's plenty of shade at Swisscare, especially when the PSH is between you and the sun.
As for children aged about 13, Wendy's 15 year old grandson will be there, half the time he will be doing his PADI course though.
I think Alan has kids around GCSE age.
It has been said though, that Rog mate and myself act like a couple of kids at times (it's my ball and I'm going home if I don't get my own way)
Nearly forgot, I can teach yours how to blow coke bubbles through their nose(s). But I can't possibly tell you what Rog can teach them, you won't come if you knew!
