We are a group of 13 including 3 young children (ages 9,4 and 2), 3 couples in our 30s and our parents in their 60s visiting Scandinavia for the 1st time this July. I need suggestions on how to plan 4 perfect days in Stockholm. We bought the 72 hour Stockholm card which we will be picking up from the Arlanda airport. We love the outdoors and also want to cover all the major highlights of the beautiful city for 3 days and perhaps devote the 4th day to explore the outskirts (suggestions?) or the archipelago. Pls share your suggestions for a 4 day Stockholm itinerary.
