We have been on at least 6 other cruises with RCI, Celebrity and Seabourn and this was our first with P&O. We were extremely disappointed to say the least, even when compared to Island Cruises: the customer service both pre and during the cruise was absolutely disgraceful.
Positives:
Excellent service re baggage collection and delivery to the cabin and likewise on the return journey
Very nice cabin with 2 TVs and lounge area.
