We went 2 days earlier than our cruise would begin and enjoyed the canal cruise which gave you a real idea of the different areas of Copenhagen, the buildings and some history. We went to Tivoli Gardens at night to see the lights and the old fashioned games and rides. We also ate dinner there which was expensive but very nice to be in the heart of all the sparkle. We saw the palace and the changing of the guard, and continued the walk to fabulous water fountain and the little mermaid. Rosenborg Castle was worthwhile and the grounds. it is a must to relax along the canal at Nyhavn and enjoy a meal, beer or even a great ice cream cone and watch the crowd.
We stayed at the Admiral Hotel which was a great location to the sites listed above and an interesting old building. We had prepaid and there was a lot of confusion about this upon checking out. Our travel agent sorted it out for us but it should not have happened. It also does not have air conditioning but fans are provided. being on the water side is nice visually but does not guarantee a quiet night with the restaurant below and the art displays with blow horns to use at all hours.
