Hey friends from across the pond. I'm a very nerdy Aussie looking forward to ~2 weeks in your great country for work from Easter. I've never been to the UK before (or even Europe) & my goal is to make the most of it that I can!

So I'll be there 6am & jet-lagged on the 30th, with that day, the 31st & the 1st free.

Then the 6th & 7th - I'll be staying in High Wycombe.

Then finally I get the 12th, 13th & fly out on the 14th at ~9pm.

I like Lego, but Legoland sounds... unappealing from what research I've already done. I like almost all Sci-fi, Fantasy (play a lot of DnD, loved Harry Potter since the first book game out etc.), fascinated by History (if you could hit only 1 castle in the entire country, which would you pick!?) & Science (follow a lot of physics & math Youtube channels, I understand like 75% of it?). I am also a musician & photographer, but not really great at either.

Outside London:

I'm strongly considering hitting Silverstone to check out the track museum, I haven't checked what it's actually like yet in my research or if any of the nearby F1 team factories have tours/museums. Also the Warhammer World in Nottingham calls my name. I am in tech & one of my favourite, if melancholy, human stories is Turing's life & contribution to technology - is Bletchley Park worth a look? Could I hit all 3 of these in a day & would it be worth it do you reckon?

In London:

The Big Ben tour sounds like it would be up my alley. I definitely want to see the Natural History Museum & Imperial War Museum. My English mate suggested that I should go to Punch & Judy in particular in Covent Garden. Will be looking into what's on in the West End as I am a fan of theatre.

Given my short bursts of time, I'm thinking I fly into Heathrow, roll over to London, spend 2 nights in London & hit up the touristy things around Westminster via the Hop-on-hop-off & do Big Ben, then the Museums etc.

Second weekend do the day trip up to Nottingham via Bletchley Park & Silverstone or across both days & a countryside castle on one or the other day - I hear they're more plentiful up north, something about 'pesky scots' my English friend said.

Final weekend... back to London for other stuff? I don't know!

Hopefully that's enough information to go off for what you can suggest & I thank you very much for your assistance in helping me to optimise my thorough enjoyment of your wonderful history & culture.

Hopefully this is an appropriate question here as I tried AskUK and unitedkingdom and they both removed the post & said go elsewhere.
