We are a Portland, OR family planning holidays in Copenhagen/Stockholm with a stopover in Amsterdam, Frankfurt, or Reykjavik on the way to or from. I would love some advice on where to stay (anyone done a home swap?) and some great activities with a son in his early teens. Thanks!

Copenhagen: Tivoli will be open http://www.tivoligardens.com/en/praktisk/aabningstider. Not sure which activities though.
In Copenhagen, I'd recommend the National Museum: http://en.natmus.dk/museums/the-national-museum-of-denmark/
And a visit to one of the castles can be fun. The Citadel could also be interesting: http://www.visitcopenhagen.com/copenhagen/the-citadel-gdk410745
I would recommend the Viking Ship Museum in Roskilde, which is about a 20 minute train ride from Copenhagen.
