I’m planning to take the girls on a boat trip along the Thames, getting on at Westminster Pier and off at Greenwich Pier. You can see the sights and point out different boats before stopping at the Cutty Sark. On weekends and during holidays, kids can meet ‘characters’ from the ship, including the captain, the cook and the man who originally built it. Older kids can even climb the rig if they want. Then, it’s back on the boat back to Westminster – a great chance for the kids to wear their pirate costumes.
