My wife is attending an international medical conference in Stockholm this September and I get to tag along. The organizers (always doctors from the host country that year) do a fantastic job of showing off their country and local culture. The last one was in Switzerland and we had simply an amazing time.
The itinerary has us spending three days in Stockholm and then another 2.5 days in Visby. We will arrive in Stockholm a day early and also have two days at the end of the trip on our own. It is these days for which I am seeking some guidance.
So far, Uppsala seems the best additional stop to visit given its proximity to the airport. Are there any other smaller towns I should consider or, given the time limitations, should I simply spend more time in Stockholm? I am sure trips will be organized to the Vasa museum and a couple other must do sites in Stockholm as part of the conference.
For background, my wife and I love exploring a place in depth and I, in particular love wandering around with my camera. We will not be renting a car.
Thanks in advance!
