As I read about the places I'm considering visiting, I'm rethinking some aspects of my itinerary.
I'd been thinking it was too much to hit Norway as part of this trip, but I could potentially take the overnight ferry from Copenhagen to Oslo and spend a few days there before heading to Stockholm. (If I do that I'd skip Kalmar.) Also, someone told me Turku is really nice, but Rick Steves isn't that high on Turku, so I might skip that as well.
There's still a lot of time to think through all of this. But I love considering all the options.
