I've done this recently but didn't get many replies so will repost. We are going to Haven Primrose Valley park near Scarborough in a few weeks time and looking for ideas of things to do with a 9 year old and a 3 year old. And if I can exchange clubcard vouchers all the better 
I think Cherry Pie suggested Robin Hood's bay and to go to Whitby, but anything else? Anything for when it's wet? And can M get a donkey ride?
She also wants to go on a ferris wheel (damn Peppa Pig going to the fair!), is there stuff like that in Scarborough??
