If you decide not to travel, then it would be best to do so in good time. We should be able to cancel your booking and refund you. (Please be aware that we do not charge fees, but the ferry operator may levy a cancellation charge, if they wish. We will have no option but to pass that cost on to you.)
We will always keep you informed of any charges that the operator wishes to make.
For advice on this matter, please contact us.
