Hello, my husband and I and our 2 children (ages 15 and 12) will be traveling to Scandinavia this summer. We're thinking of spending about 2 weeks there and want to cover Norway, Sweden, and Denmark. We're looking for a mix of city exploration, nature, and some unique experiences that the kids will enjoy. Has anyone done a similar trip with teenagers? Any must-see spots or hidden gems you'd recommend? Also, any advice on moving between countries efficiently would be super helpful. Thanks in advance!
