I'm considering booking a short break at Chessington for me, DH and our 3 DS (7, 5, 3) in the summer holidays, probably Tuesday 22nd-Wednesday 23rd August.
Am I insane? 
We took the DC out of school for a few days to do Legoland a couple of years ago and the lack of queues was fab. Am I letting myself in for a world of pain by going in August? I'm kidding myself that it might not be too bad on a Tuesday/Wednesday...
Thanks for any insights!
