How this site earns money
Some links on this site go to booking sites such as GetYourGuide and Viator. If you book through them, we earn a small commission. The price you pay is the same.
That commission pays for the time it takes to check every quay, opening hour and timetable against official sources, and to go through it all again each season. It also means no ads and no pop-ups.
When a free option or the ship's own excursion is the better choice, we say so.
