Hello. I will be arriving in Copenhagen from Luxembourg around 7:15 PM on July 2nd. My flight to the USA doesn't depart until 12:30 PM the following day. I have booked a night at a hostel right next to the main train station. My question is do you think I will have enough time to get a quick overview of Copenhagen in the few hours I have there? I was hoping to see Christiansborg Palace, Amalienborg Palace, the Marble Church, the Little Mermaid, Rosenborg Castle, and the Church of our Savior. I probably wouldn't be able to go into any of these places but I'd be happy just to see the buildings and take some pictures. I was thinking of exploring the city between about 8 PM and midnight on the 2nd and then getting up early and going out from about 5:30 to 10 the next morning. Do you think this is possible or am I being too ambitious?
