Fred Olsen Cruise Lines has amended its policy to widen the appeal of round UK cruises.
Those who do not hold a passport or photo card driving licence will be able to board if they can produce other acceptable forms of photographic identification at check-in.
These include a bus pass, travelcard or forearms licence.
These forms of photographic identification ensure that the line continues to meet its policy of being able to verify the identity of each passenger and comply fully with the requirements of the International Ship and Port Facility Security Code, Fred Olsen said.
The revised policy excludes any itineraries calling in Ireland but covers three departures this year.
Sales and marketing director Nathan Philpot said: “One of our most popular range of cruise holidays is our around UK voyages, where guests can experience the many delights of England, Wales, Scotland and Northern Ireland, in a simple, stress-free way.
“We are now making it even easier for that proportion of the UK population who do not have a passport or photo card driving licence to enjoy our in-depth UK cruise experience, and get the chance to visit UK towns and cities that our smaller-sized ships can access.”
