NB bestie getting married!(Civil partnership in UK)

I have no idea if they're in this sub but Quinn if you're reading, don't look further!

So my bestie is getting their civil partnership ceremony in the UK next year and although it's not an official marriage, I'm helping them celebrate like it is one which includes a sten/hag party 😂 they're really into films, books, heavily into the queer scene (and as an ace lesbian I am also heavily in the scene), I just wondered if Reddit could help me with activities to do or ideas that would contribute towards the most amazing combined party for them and potentially their partner, so I think it'll be a joined event.

I've planned a scavenger hunt for a different wedding so I've got experience with that but if anyone has any other ideas I'm all ears! 💜
