I'm in Norway. While the sun technically goes down, it just goes barely below the horizon so we just have a few hours of civil twilight and if there are a few clouds, a sunset that lasts for hours until the sun comes back up. I can read outside so long as it isn't too cloudy - and barely need light to do so if it is.
It is pretty glorious, though some folks do need to darken their bedroom to sleep well - especially immigrants.
Immigrant in Norway. Can confirm. First few years were tough, but now I don't even bother with curtains. Summers here are the best (provided the weather isn't awful).
I was kind of lucky myself - I worked nights and was used to sleeping when light outside. And you are right - summers are pretty wonderful, though I like it when the summers are cool.
After 7 years here, I still don't recommend swimming in a pond on a mountaintop. The water is still cold.
Another Scot here (NE Scotland). While it never gets properly dark during summer, it comes with the caveat of feeling like it's permanently dark during winter. I always hated driving to work in the morning in the dark, then driving home in the evening in the dark. Winter here feels kind of depressing because it's dark so much.
Also, IMO, unless you've got proper black-out blinds, never getting dark during summer is a PITA!
Similarly, I am in St Petersburg Russia, and white nights, while taking a little to get used to, are very pretty. You have to make a major adjustment though in the form of heavy window drapes ).
But since I moved to Russia, I have thoroughly enjoyed no DST, it really is a headache for a lot of things and it's more annoying to work with our colleagues in the US and EU who do respect DST as we have to add just that much more planning. DST is an artifact we don't need anymore.
Out of interest why would you be annoyed - here in Scotland it's still light at that time in summer and it is glorious - best time of the year.
