I would not mind being 50 again. We were there recently. A few things that you might not hear elsewhere: There is quite a good and free (but for tips) walking tour of Reykjavik. Also, Reykjavik has an art museum located in three parts of town. The one in the middle has an Icelandic artist named Kjarval. We thought he was world-class, though his works hardly ever travel, so he is not well known outside of Iceland. Also, English is sort of the second official language. Because a lot of foreign born people work in Iceland and they don't speak Icelandic, it seemed almost everyone spoke good English. Iceland gets about four times as many tourists as it has residents! If I had to do it again, I would travel to the north coast and go whale watching. I would also check out the volcanos. Iceland is very expensive, maybe double what a comparable vacation would cost in the US. Just accept that fact, and you will have a good time. We loved it. I would stay at a hotel (as opposed to, e.g., Airbnb). It is very helpful to have someone who knows the area and can give advice. Pick a hotel close to the town center. We were quite happy with Hotel Hilda.
