P&O Cruises has replaced six short UK cruises due to depart this summer with three week-long itineraries “following guest feedback”.
In an update on its Facebook page, the line said that six three and four-night breaks on Britannia which were due to run between August 29 and September 16 would now be replaced by the longer sailings.
The domestic sailings went on sale on Monday, with the line blaming unprecedented demand after its online systems crashed.
It confirmed on Friday that customers who had already booked the shorter itineraries were being contacted and advised of their options.
The post said: “Following guest feedback and demand for week-long UK holidays, we are replacing six of Britannia’s 3 and 4-night breaks (from August 29 to September 16 inclusive), which went on sale earlier this week, with three 7-night cruises.
“We have seen this week that the 7-night holidays are proving very popular so we are pleased that we are able to add three more of these to the series of UK coastal cruises this summer.”
It added: “We apologise to the guests who had bookings on Britannia’s six short breaks which have been replaced and we are contacting them directly today and advising them of the options for their holiday.”
The three new cruises will go on sale at 8.30am on Tuesday (March 30). They will each feature a UK port of call and “a range of new shore experiences”.
