Fantastic photos - you've been so fortunate with the weather it looks like.
I spent many summers and a few winters as a kid in Tromsø because my mum had a partner from the island of Senja, which is just off Tromsø. This is back in the 90s before the coast became fished out, and my mum and I would go fishing until 4am some times. Huge cod fish!
Are you on the cruise ship for the duration? I did my military service in Bergen (plus 8 week boot camp in Stavanger) and Bergen is a wonderful city. A bit too rainy for my taste but I made some friends for life there that I am still in touch with.
I can't say I'm homesick for Norway but I can appreciate the beauty of it. I'm heading to Norway next year for 5-6 weeks in July/August, but it's with two young kids so we won't travel Norway as much as you are doing right now.
