I am sure many of you know but for those who dont…there is a Annual pass called Merlin pass which allows you to enter 14-15 top attractions for whole year…family of 4 go for 375 a year…if u use it regular then it works out cheap…my friend calculated that if a family visited all the attractions once it will cost around 900 but with this pass u can go as many times…
or have ya kids adopted and spend that £375 on fuel for bike and have a whale of a time 
You could send them out with cameras to accident black spots and get them to play “Spot the biker down”
I will be locking mine in their rooms while i go to the LB BBQ:D
+1:D
You could probably sell the kids and have £675 to spend on fuel
