Thank you! Could you please tell me how much you think you got more ?

I exchanged 3000 Danish kroner and 10,000 Norwegian kroner. At the time, I thought that driving in Norway was mostly in the mountains and that credit cards might not be as convenient. But I really underestimated developed countries. In the end, I really had to use cash for everything, including hotel stays and gas, to barely finish spending. If you're really worried, you can exchange a few thousand extra. You don't need too much for real. I stayed in Denmark for 6 days and Norway for 7 days. Anyway, once you exchange cash, you have to spend it all otherwise it's too much of a loss to exchange it back.
