I have been on many cruises with various cruise line. This has been my 5th P & O and I must say after this trip I will never sail with P & O again.
The cabins are so small that you don't even have room for your luggage when you empty it. Not even under the bed which is where you normally would store it.
The entertainment was very average. The food was below standard except for the in 400 Gradi, which was excellent.
