Legoland is great. There are lots of deals around for entry at the moment - only problem is it does get very busy on weekends and school holidays at this time of year and the queues can be horrible.

Windsor Castle is great and a boat trip from Windsor - great day out.

Cotswold Water Park is a great place, they could try kayaking.

What about Go Ape? I sthat expensive?

Also, there is that new playground near us isn't there, maybe walk with the dogs, play there then camping in the backgarden with movies on a laptop or something. I bet they'd love that!

Go Ape is great but only lasts for as long it takes them to get round, also quite dear from memory.

I think ideas around the boat trip with them driving would be the coolest. It is not everyday they get that chance. Could you combine it with a barbeque on a small beach somehwere? If you were feeling adventurous you could also have pre buried some treasure and give them a scavenger hunt to finish off with. roasting things over a small fire also goes down well with boys of that age!
