Touristic Question (Copenhagen)

Hi Copenhagen community,

I am seeking for your advice and simple suggestion about the best way to kill Protected content (during the daylight) in Copenhagen.

All the big touristic places (Little Mermaid, Royal Palace & museums) will be covered the next day with a group of friends. So it's more like: How to spend time wisely while waiting for them to arrive :)

I am planning to stroll along the Strøget pedestrian, going to Kongen Nytorv and finally Nyhavn, but I think it won't take too much time (?) and also, is there any specific place that I could look into?

Many thanks in advance :)
Bella
