What we learned (and already knew) is that we should never do another trip with two connections. Bad idea. Next time, we'll drive down to Chicago and catch a direct flight to Stockholm. I don't care if it is a bit more expensive.
Anyway, now I am down with a bad cold (typical vacation fare) and will be in bed for most of the day, while the rest of the gang take the commuter train into Stockholm for a day on the town. My goal is to recover fully today and be ready to go tomorrow.
Tomorrow is a new day.
