Aurora's theatre seating must be the most uncomfortable at sea, for wheelchair users Carmen's is very poor, and the sun deck has no auto doors.
The main pool area is very weird, and again very wheelchair unfriendly, and there are a number of corridor endings with only stairs.
The standard cabin cut out balconies are nowhere near as user friendly as even Britannia's tiny juliet ones.
But I am glad so many of you love her, and are prepared to pay premium prices to cruise on her, which seems to leave P&O with the need to keep the pricing of the bigger ships so very competitive.
