You are going to love it. I took my first solo trip last year for the Flower and Garden Festival. It was great fun so I scheduled myself another one.
Mine are much shorter than yours though. Does your wife like the Laila perfume in Norway? If she has tried it and liked it, that would be a really special gift.
Or does she like nice scarves? I found some gorgeous ones in China and Japan.
For MK, I love the glass store. Maybe something from there?
Have a great time!
