Need a day out from London?
Couple of thoughts:
1.) Yes, if anyone enjoys tennis, then a tour of Wimbledon is worth it.
2.) Does anyone in the family watch Ted Lasso?
If yes then head to Richmond. My hidden gem of a pub there is the Angel and the Crown. Nearby Richmond Park is a pleasant meander. Do lunch at the White Cross pub and then stroll to the Ham House and gardens. From there walk along the Thames River path to Rotary Gardens. Walk up the path and make your way to Teddington Cheese. Small shop. Great cheeses. Next door to the proper The Victoria Inn pub.
3.) Bletchley Park is worth a visit. Home to the WW2 codebreakers. https://bletchleypark.org.uk/
I spent over 4 hours there.
4.) The Hampstead Heath is nice to meander about. If lucky you might find a rugby match to watch. https://www.hampsteadrugbyclub.co.uk/
5.) Lastly, I’d consider visiting the Shoreditch neighborhood to see the wall murals. You can sign up for a tour or meander on your own.
Think you’d like lunch at The Box Cars or from a stall in Spitalfields Market.

Brick Lane is close by Spitalfields. Always interesting.
