Every time I visit Oslo I am moved by the Vigeland sculptures. They seem so much more human than anything by Michelangelo or other famous artists. I could spend a day in the park, but after an hour usually continue two tram stops north to the Majorsteuen metro station (T-bahn) for a ride on the #1 train westbound to the end of the line on a mountain overlooking the city and the fjord. One can take photos from the train platform and return to town by train. I prefer to walk 30-45 minutes downhill on a wide gravel pathway (lighted at night for cross-country skiers) to the Holmenkollen train station, passing a scenic stave church and the bottom of the famous ski jump on the way. Alternately, the Holmenkollen restaurant veranda, a short walk uphill from the Holmenkollen station, has gorgeous views overlooking the city.
I suggest then taking the train back to the national theater downtown, for a view back to the palace and a short walk to the national art gallery, which is behind the university plaza. The museum is closed on Monday. It has a very enjoyable (and free) collection of impressionists, and some fantastic paintings by Edvard Munch (including one of the four versions of the famous "Scream" another was stolen from Oslos Munch museum, hence the heavy security at both museums).
From the art museum, continue walking east along the main shopping street. The stores, parks, and people are all beautiful here. When it is time to return to the ship, walk back via the old fortress (Askerhus). The view of the ship from the ramparts is great (the ship dwarfs the fortress), and there is a back gate which leads down a short path to the pier at the south end of the fortress.
An alternative to the above Oslo options is to take the public ferry or bus from the city hall square to Bygdoy island, which has several museums, including an open-air folk museum, the Kon-tiki museum, the Fram museum, the maritime museum, and a Viking ship museum. Each of these has a separate entrance fee, but each is accessible on the Olso day card, which is expensive and is available at the tourist information office when it opens in the morning. We enjoy these options when we have more time in Oslo.
Ending The Cruise: By now you are exhausted and ready to return home. Disembarkation in Copenhagen begins shortly after the ship is cleared (about 0615) and continues till about 1000. Passengers are given color-coded tags for their bags, which are left out in the hall the night before. I do not know how long baggage claim and clearance takes at the dock side since we have never cruised with more than a carry-on. I believe that baggage transfers to the airport are handled by the cruise line if you buy their transfer package.
Again, the cruise line suggests not booking any return flights from CPH before 1130. Again, for independent travelers the short walk and then train from the ship to the airport takes about an hour. Taxis are inadequate at dockside -- the lines are very long. With all the other cruisers flying home too, allow another hour for check-in at the airport.
Final Thoughts: Dont worry, be happy, and have a wonderful time on your cruise!
