DH randomly booked a hotel for me in London as I've had a rotten time recently and I've wanted a solo trip to London to do museums etc for a long time. However now he's done it I'm feeling a bit overwhelmed and anxious, so for those of you who live in London can you help me get my head around using the tube? Do you just use contactless or will I need an oyster card? I'll also need to get a bus from Archway to Highgate cemetery on Tuesday morning and I've never used a London bus. Do you use money or contactless?
Sorry for the silly questions but I'm feeling quite anxious and overwhelmed about it all!
