I was going to sail on Cunard on a similar itinerary but wanted something less formal. Boarding was not great. I arrived early and despite there being no queues to board at that time, they made me wait for 2 hours, so not a good start. My cabin was great and huge but there was mildew on the tiles in the bathroom, something that can be easily cleaned, right P&O?? I chose the relaxed dining but was still required to join a queue on the app etc, it felt they were pushing me to spend money in the other restaurants etc. Other than that, nice ship, nice spaces, probably too many kids for my liking but this wasn't advertised as an adults only sailing so you can't win em all. It would be nice to be able to have a hot breakfast in my room, they now only do continental.
