I rather fear they will not even get ON the ship in the first place without a passport as this is only means of formal identity we have in the UK.......Wilba.
You definitely need a passport to leave or enter the UK........Brian
I hope this information will be of help. I have friends taking a 90 year old aunt on Fred Olsen's Black Watch cruise around the UK and Ireland in May 2009. The cruise was given as a surprise Christmas present. The person concerned does not have a passport and this was queried at the time of booking and she was accepted for travel. If you look at Fred Olsen's website under Passports in the A-Z section, you can read the following: For UK and Eire Only Cruises, a valid photo ID Driving License is accepted in lieu of a passport. European ID Cards will be accepted for visits to EC countries. I wouldn't imagine the 90 year old passenger has a valid photo ID Driving License, but I could be surprised! If you give Fred Olsen Cruises a call, they may be able to confirm that other forms of photo ID in lieu of a driving license are acceptable for cruises in the UK and Eire. Regards Jan .
