To add an adult to your booking, you can proceed directly with a new booking for them through our website. If you have concerns about seat allocation, the ferry's crew can assist you upon boarding.
In case you need to include another adult in a cabin, you can either cancel the current reservation via the "My Booking" page, if you are still eligible for a full refund according to your ferry operator's policy, through "My Booking" page and book the correct cabin type, or reach out to our team via chat for assistance.
For adding a child or infant, online bookings are not possible due to restrictions on unaccompanied minors. Please contact our customer support team via chat, and we'll be happy to assist you. Since you already have a reservation, we exceptionally waive the 6€ service fee, and you will only have to pay the ticket price.
