Any suggestions for an (outdoor) day out between Surrey and Worcestershire?

[Donatella]

A friend and I are making plans to (finally) meet up with our kids in the Easter holidays, after the restrictions are hopefully eased on the 12th. Normally one of us would travel to the other and stay overnight but that won't be allowed so we need to find somewhere to meet up approximately half way that will a) be open and b) amuse a mixture of boys and girls aged 6-13. Any suggestions? Current front runner is Cotswolds Wildlife Park as we have been there before but open to other suggestions.

Bump

Blenheim Palace (if the maze and miniature train open on the 12th) or Wendover Woods (has a Go Ape).
It’s a little out of your way, but Woburn Safari Park and Whipsnade Zoo.

Ooh, Blenheim could be good, I think some of DH's family used to be in service there, although it might be better when we can go inside. Will check out the others, thanks

Waddesdon is great and should work distance wise
