When the final number of passengers is known, you can contact us on +33 (0)3 69 74 44 04 during office hours or at info@batorama.com or even report it at the ticket office when picking up your tickets. Increasing the number of seats depends on the number of seats remaining on the boat when you apply. Please note that the decrease in the number of seats is free if more than 24 hours' notice is given. For less than 24 hours' notice and a decrease by more than 9 seats, cancellation fees will apply. Changes are not possible and tickets are not refundable one hour before departure.
