Troll, since I've become a parent as such, we've been looking at wowcher and groupon loads to see if there are any places both would like because they're close in age but one is wild and the other dead shy, so we get stuck doing same walks etc.
The quiet one would sit and read with a cocoa and the mental one would throw axes whilst drinking pints if we allowed it.
We're trying to find something that hits the sweet spot for both so we've been going safari Park, zoos and are planning blackpool soon.
Everything is dead fucking expensive if you can't bum it for free but we've found they like old fashioned pubs with a garden outside, delamere forest and loads of walks. It knackers them out and the little one likes to push his own buggy. Tried to throw it into a canal once lol.
We also split the day in 2, so our psycho one gets to go wild and then our shy boy goes to somewhere he likes, so coffee shops or Waterstones in town. It's proper graft this mum stuff, dunno how truff does it
As long as they're getting fed, they're generally pleased tho, that's the highlight of any day out, scran. Like me!
We've considered national trust places for warmer months. Might be boring for your older one tho?
