What are the transportation options and costs to get from the Freeport Cruise terminal the the Central Rail Station and Tivoli Gardens?
Robert, I suggest you post question under transportation. I received a lot of help from them.
We were in Copenhagen in June. We took the S-tog train from the Central Station (Tivoli is right across the street) to the Nordhavn station to catch our ferry boat to Oslo. If your ship docks just North of the Little Mermaid, a map I brought home says bus 26 goes directly from there to the Central Station. I don't recall the exact fare, but either train or bus would be a few dollars per person.
Happy travels.
