Royal would do well adding another ship out of Southampton that does some more interesting itineraries to give more options.
The P&O comparison is fair though, yes the ships generally aren't as good, Azura is shockingly bad in some many ways, design and the vibrations if you get a rear cabin and horrendous. But in saying all of that the food and service we thought were fine and we went with kids in a school holiday. Also good to hear the comments from people that said they didn't know it was a school holiday - when it literally says it EVERYWHERE when you search and book, that makes me laugh a lot.
RCI can still make good money out of the UK / Northern Europe routes but they need to offer something a little different. Have Anthem go south in the summer and Navigator go north / Scandinavia etc. would be great for those that don't just want the sun as an alternative. Come on Royal, throw us another ship or at least two..!
