I tried it on Britannia last year but to get to a USB socket on the back of the TV you have to remove it from the wall first.
I managed to get it off then found a warning on the back about connecting devices to the USB so I put it back on the wall with some difficulty and it didn't look right.
Next time we returned to the cabin the TV appeared to be as it should be BUT, shortly after, our steward apologised to us and said that the TV must have been badly fitted as it fell off when he was cleaning and they had to fit a new one!!
Keep well clear!!
At a time when we are supposedly suffering a cost of living crisis, I am surprised at the, apparant, amount of people with loads of cash under their mattresses that could be earning at least 3% interest in a local building society.
Just checked the website for this cruise again and as previously stated SPB has been removed from the itinerary map but look at the description given for this cruise : -
I think what probably happened is that they had to change the web site listing as it originally showed a visit to SPB on the itinerary map. Having done that they then probably also changed the title to encourage sales.
On 'My P&O Cruises' the map still shows a visit to SPB but the written itinerary does not.
Who knows what's going to happen? Certainly not P&O!
You can find it by searching for May 2023 cruises on Britannia but it's a bit worrying that Baltic doesn't appear in the search option.
I noticed that the title for the cruise is now Northern Europe And Scandinavia, no mention of Baltic, so maybe they've changed it. According to My P&O Cruises it is entitled Baltic as it is on websites other than P&O.
