When were you there last? While I agree with everything else you say, Reykjavik has over the last decade or so unfortunately turned into a city of souvenir shops and tourist trap restaurants. Personally I wouldn't 'budget' more than 24 hours of an Iceland vacation to Reykjavik.
Unfortunately the US will never get to be the utopia that is Iceland in terms of safety and taking care of its citizens so crime doesn't need to be committed. It's too big with half the population just thinking like their parents and grandparents do or did vs. thinking hmm I'm open minded to see how other countries work.
Love Iceland!
P.s. I'm still chasing the lights and had flight to Fairbanks Alaska scheduled last Tuesday to stay for a week. I had made my flight I would've seen them. Got to be nimble ..just got drop whatever and get a way to where it's forecasted to beam and then hope for the best.
I didn't see the lights but fell in love with Iceland. If you really want to see them you have to hunt and chase them! Like tonight Alaska is the place to be!
