This is a good overview of Copenhagen. Our guide was well informed and explains well. We visited the major sights like the Amalienborg during the changing of the guards, the Little Mermaid, the Gefion Fountain and Nyhavn.
I booked this tour knowing that a Zurich city tour is included but days after I paid for the tour, they e-mailed me that the city tour would not be included. I ended up not having toured the city at all.
This is a great tour starting with a free time in Lucerne and then the trip to Mt. Titlis. If you want to see snow all around you, this is a good tour to take. They even provide free use of a heavy jacket and snow boots as long as you request at the time of booking.
