In the decent-sized cities of Norway, Club Carlson can be good.

But get out into the smaller towns on the western fjords, and all you'll find in terms of chain hotels is Choice here and Best Western there (but probably more Choice than Best Western, though with the distances involved depending on where you want to go you might have you use for both programs).

I presume that where Club Carlson works vs where only Choice works is similar elsewhere in Scandinavia, but I haven't done that evaluation for countries other than Norway yet.
