Advice mmm. Well I would say ....DONT DO IT...book into a nice little hotel, where you can use a proper toilet, wash, keep dry, and sleep well. Let him sleep on his bedroom floor, he'll soon get bored.
If you decide to camp anyway then I suggest wellies and lots of layers, even in the summer it can get chilly in the evenings and at night. Goodies for a feast and plenty of liquid esstentials for grown ups

You wont need an alarm clock if you camp anywhere near us thats for sure.
Joe, it really is good in all honesty. The evening social side is great but dont tell the others I said so.
