Very interesting but very bad organization. I arrived 20 minutes early, I stood in a 20-minute queue in the middle of people who were buying drinks, gadgets…. After drinking 20 minutes, I was given tickets for a departure at 4:30 p.m. when I had booked for 2 p.m. and that the boat was still there and that there were still our places. I argued with the captain who ended up taking us on board but I was very angry.

Very easy to book via the app, but you then have to have the ticket “validated” and go to the counter again. You can also get the headphones there. What I didn't like was that the headphones were thrown away instead of being disinfected. That results in a lot of rubbish during the day. Otherwise the tour was great, you get great information and can enjoy the ride very relaxed

The organization was great and the ship and Martin, our captain, were very good. Unfortunately I deduct 1 star because I had booked an audio guide in German, but very little information came across here. There was a lot more from the captain, but then in English, which was exhausting for us.
