With Ferryhopper's multi-destination feature, you can combine multiple destinations in a single booking and effortlessly plan multiple itineraries, even with different ferry operators.
During the first step of the booking process, choose "Island hopping" instead of "One-way / Return". Then, select the departure port and add up to 4 destinations, along with the respective dates.
Kindly note that you can choose a different ferry company for each trip, but you cannot change passengers/vehicles among trips.
