I am taking my twin boys to Denmark for 10 days. And am stuck with what to do in the middle of the trip. We land in Copenhagen Saturday June 4th and pick up a rental car. Heading to Billund staying on a farm and going to Legoland for one day. And I have an Airbnb rented from June 10-14 in Copenhagen. I am just not sure what to else to do. Since I am traveling with toddlers I only want to stay in one other place. I thoughts were head to Silkeborg and Aarhus, staying probably in Aarhus. but I am completely open to suggestions.
