We flew into Copenhagen a couple of days early for the Baltic cruise and then spent another day there after the cruise.  It is a beautiful city with a lot of offer and see.  

The Tivoli Gardens Amusement park is a combination of rides, restaurants and shows set in a beautifully gardened setting right in the middle of the city. It was a really cool place.  The water cruise through the canals was a first for us and a great way to see the city. Just a great city.
