All in all it was a very nice trip. Helsinki, while not the most thrilling city in Europe, is very tourist-friendly. It's incredibly easy to get around, the Helsinki Card make sight seeing and transportation quite affordable, and the whole environment is rather calm and relaxing. Would I come back? Probably not, unless it was part of another trip I wanted to make. Helsinki strikes me more as being a great place to live than a place to keep revisiting (like my favorite of favorites, London). That said, I do think that if I ever needed a place to go to get away from accelerated global warming, Helsinki could be a great place to live -- provided I learn Finnish and take sunny vacations in the winter so I don't die of Seasonal Affective Disorder.
Next -land on my list? Most likely Scotland, next May.
