We did an excursion through the ship which included a canal ride. It was enjoyable and the guide informative. Copenhagen is a cute little city but I expected more. I didn't leave wishing I could have more time there.
Comfortable bikes (no gears but not really needed) and a great city to bike around (flat and good bike lanes). The guide was helpful but didn't always have too much to say about the sites we saw. We really enjoyed Helsinki and recommend seeing it from bicycle.
You have to get to the visitors center to meet the guide and then walk back from the bike shop (8 blocks further away) after the tour so taking a taxi would make more sense than the boat shuttle which was expensive, not that convenient and had a long line going back.
Great van, Great guide, saw every major site and had a nice sit-down lunch both days. Only complaint was some confusion on the 1st day in organizing the groups on to the buses which didn't make sense because we had pre-arranged our groups on cruise critic before the trip. Anyway, I'd highly recommend this tour and Masha our guide.
Great way to see the city and great guide but the bikes were not that comfortable. They are new 21 gear bikes but have a hard racing seat and low handle bars. The "ladies" bikes with the cushion seats were already rented so I'd recommend reserving one if you do this tour.
