Compare cabins, meals and port transfers together
Begin with the same people, vehicle and travel dates. On overnight routes, compare the accommodation your party needs, not an advertised entry price that uses a different cabin or passenger count. Harwich overnight cabins are compulsory; Hull and Newcastle products have their own accommodation rules.
Check whether meals and city transfers are included in the fare you selected. A mini-cruise, combined rail offer and ordinary one-way ferry ticket can have different inclusions. For Hull–Rotterdam, transfer coaches exclude ordinary pets and full-size bicycles under P&O’s current guidance, so those travellers need another arrangement.
Use the dated timetable for duration. The Netherlands is one hour ahead of the UK: subtracting local clock times without correcting the time zone gives the wrong elapsed journey. Also allow time for disembarkation and any border checks before a train or appointment.
