I'm going to go and stay in Copenhagen solo for around 5 days in November in 10 days and I'll be honest I'm a little nervous. I've travelled before on my own to Edinburgh and Belfast but I feel like I haven't prepared enough for it even though I got the basics I need : Warm coat, power adapter, enough clothes, debit card due to it being a cashless city (I'm not sure how transaction fees work abroad)

Is there any tips that you can give me about the city and things to do. Towards the end of my trip I want to visit Malmo.
