We booked our first P&O cruise a year before COVID with some trepidation, because we had the impression it was a notch below most of the larger mainstream companies. Even our travel agent warned us against it. However, the itinerary and timing suited us perfectly and we went ahead.
Long story short, it was a lovely cruise, on par with Princess and Royal Caribbean cruises we have taken out of Sydney (including the "busy" factor). We liked it so much that we have booked again next year for my 65th birthday, this time in an aft-facing suite. Really looking forward to it!
