Hi, I'll have 4-5 (maybe 6 days) for solo travel this summer, and I'm considering Europe. Specifically, I would depart the US on July 29 and fly home August 3 or 4. I know this is criminally short, but (a) I'll use points and/or low-cost carriers, (b) long flights and jetlag don't bother me, and (c) I'll be solo and won't have to listen to anyone else complain ; ). So, let's assume I've made peace with this crazy plan. My choices will be constrained by flight schedules and fares/points, but I've done some initial searches and I think I can make this work.
As I review my options, I'd love some opinions on destinations that can be "done" in 4-5 days and stand on their own (or are very close and could be paired open-jaw). No real agenda, other than to soak up the city and see some obvious sites. I love to hike so would consider the mountains instead, but transit time might eat up too much of my already short window.
My first thought is Scandinavia, because (a) I've always wanted to go, (b) a solo trip for a few days would be a relatively cheap way to do it, and (c) cooler temps and lots of daylight. I've only been to Copenhagen for one cold day and would gladly return. Another idea is Amsterdam, or more generally the Netherlands. I'm going to Paris in April, so let's rule that out. London might work, but award tickets there carry huge taxes. And Iceland is alluring, since it's closer and has cheap airlines (but not sure it can be properly done in 4-5 days).
As much as I'd love to explore the Baltics and Central / Eastern Europe, the transit time is a problem. (Prague or Budapest might be doable.) And it seems too hot for Iberia or Italy.
(And if I can't swing this, the RS PNW crowd will be happy to know my other idea is their neck of the woods ; ).
