My eldest, aged 12, is a massive Doctor Who fan. Particularly in to the Troughton & Pertwee era, with an impressive DVD collection to prove it. Pre-COVID, we used to visit the annual Doctor Who convention at the National Space Centre in Leicester. Highlight was getting his photo taken with Sylvester McCoy in a mocked up Tardis. He was beaming for days afterwards.
The Space Centre do some good stuff. I met Chewbacca last year.
