I highly recommend a visit! I went a few years ago and had a great time. It's right at the top of Bletchley Park and only costs a few pounds. It's a bit of a shame that it feels neglected by the main museum (it's a separate area/exhibit/entrance to the main Bletchley Park museum). Easy to get to from London, regular trains run from Euston all day.
I took a bunch of photos when I visited [1], I could've easily spent days there. It's unlike any museum I've been to before, towards the "end" there are lots of rooms with just piles of books and computers you can sit down with for however long you wanted - lots of tactile interaction! It was also wonderful to see machines like Colossus running as well as all manner of oddities like early UNIX systems, air traffic computers and calculators.
I loved the games room at the end of the museum. Great way to transition from all the interesting history, from all the invoked thoughts of how high the stakes were for cracking Enigma, to seeing how technology and computers can improve our lives and make us happy.
