Mine are lazy teens, my DS would love to lard about doing nothing, DD would go shopping 
But when they were little:
there's a visitor centre, nice walks, lake, geese, deer (we used to go on Christmas Eve) a little teashop.
Put on wellies,gloves,warm coats. Take a bag for all the treasures they collect
we went to London, counted the Hamleys bags on Regent St.
Food at McD (High life eh?)
Cinema (DH used to take them while I went to Sainsburys in peace)
Take the DC out on their own to buy a present for their sibling
Make cakes, chocolate crispie cakes, cookies
(I miss the years with little DC now. )
