A further possibly final comment on food quality comparison.
We had afternoon tea in the buffet the other day, and as well as warm freshly baked scones, they had genuine clotted cream as well as jam, and we also had a couple of the sandwiches, and desserts which were delicious. The P&O chefs should take lessons from Princess in how to make edible pastry.
We watched the wait staff in the buffet today and were impressed with how efficient they all were, ensuring tables were cleared quickly, and the tea, coffee and juice service is also very efficient, and the orange juice is stronger and sweeter than the watery stuff provided on P&O.
You will have gathered from my posts that I am far more impressed with Princess service and food quality standards than with P&O, but rather than bore everyone with a final update, I will be happy to answer any specific points you might have.
