Hi, if you decide to do the West Moors/Wimborne thing, drop me a message and I could probably give you a lift from Bournemouth and back. I live near West Moors Park and walk my dogs there every day, your 11-year old would probably enjoy it, as it has Go Ape and a decent steam railway. You can also hire bikes and there are some excellent trails in the woods.
Thanks for replying to my chess thread - would be good to have you on board. So go to chess.com. Then set yourself up an account. Next message me there and I'll get back to you. My username is Heathcliffe256.
