Three Danish Castles near Copenhagen
When your cruise ship is docked in Copenhagen, you might want to do a short driving tour into the Danish countryside and see three castles (or slots, as they are called in Denmark)--Frederiksborg Slot, Fredensborg Slot, and Kronborg Slot.
Frederiksborg is huge and a picture-perfect castle in a beautiful setting. It's often called the "Danish Versailles". Fredensborg Slot is still used by the Danish royal family as a summer residence. Kronborg Slot is perhaps the most interesting of the three Danish castles. Although Shakespeare never visited Kronborg, he renamed the castle Elsinore and made it the setting of his famous play, "Hamlet".

Paris is an embarkation port for Seine River cruises and is also a port of call for ocean cruises docking in Normandy. The City of Lights is also a perfect add-on extension for other European cruises.
