So, Sweden is a pretty incredible place.
I just came back from Stockholm where I stayed from Thursday (Aug. 1st) to Sunday (Aug. 4th), and I can say with confidence that Sweden isn’t entirely what I expected it to be…it’s more!
We arrived on Thursday at noon. Immediately, we converted 200 Norwegian kroner ($33.72) to 210 Swedish kronor (not including the exchange fee, of course; that made it only about 180 Swedish kronor), but it turns out we didn’t need the cash during the trip as cards work perfectly fine just about everywhere. This includes on the plane itself. My conclusion is that I don’t think it’s necessary to have more than a small emergency stock of Swedish cash on you in Stockholm, likely because Sweden is a pretty high-tech country and Stockholm is a very international city.
