Fantastic 2 day tour worth every penny (lots of pennies!). We saw so much with a superb guide whose English was excellent and her knowledge immense. Booked on friend's recommendation who had used DenRus the previous year. Definitely saw more privately than we would have done using the ship's excursions.
Ship's shuttle bus to town centre then used Hop-on Hop-off buses to go round town. The Sibelius Park with its enormous organ pipe memorial was impressive and the Sibelius Museum which we came across by accident was very interesting. We would have like more time here as there was a lot to see. The Church created out of the rock face is worth a visit too.
We took the ship's shuttle service into town and then used the Hop-on Hop-off buses which were excellent and enabled us to see many of the interesting places in Copenhagen. The Tivoli Gardens were, we thought, quite expensive just to walk round but we felt as we were there we should see them.
