I have always found that there are always quite a few single people on P&O cruises and there are meetings arranged for singles. Don't think you will be a fish out of water. On our last Ventura cruise in Oct we met a lady of 87 travelling on her own as well as a few others of all ages. Ventura is a very nice ship and we enjoyed it. Seems to me it was the passengers that were the trouble at Christmas not the ship. Incidentally, we are going again on the Ventura transatlantic in March...same as you?
Thanks for your prompt & reassuring answer. I was very tempted to cancel but would have lost a lot of money by doing so at this late stage. The brochure I booked the trip from did say it was 'the perfect family holiday' but other ships I have been on have been described as such & there never was a problem. I assumed all P&O ships would be of a similar standard but I guess anyone who pays the required fare gets to go..(Cabin A235 ) Lets hope the Xmas trip was a learning experience for the Staff and they have found a way to deal with unpleasantness on board.
