We will be traveling with our three kids (12, 10, 7 y/o) to Copenhagen the last week of May for about 9 days. We had intended to stay in and around Copenhagen the entire time but I'm beginning to wonder if we are going to regret going all that way and not squeezing in a few more destinations in Scandinavia? We like to travel on a budget and our kids are pretty good at going with the flow and long journeys by rail, etc., so we're open to a night train or other options that might save money short of getting multiple hotels (we were originally planning an Airbnb just outside of Copenhagen for the entire time). Before we delve deeper into fine-tuning our itinerary, I'd love to hear thoughts on whether spending all that time in Copenhagen with only a day trip or two added in is going to be overkill in Copenhagen and whether we should be planning to add in other Scandinavian destinations to make the most of our trip---in other words, should I be ordering Rick Steves Denmark or Rick Steves Scandinavia on Amazon in order to most effectively plan?
Any advice appreciated. Thanks!!
