Arcadia is an Adult only ship which suits me. Took my mum and a friend and we shared an inside cabin which was larger than many inside ones. Embarkation and disembarkation went very smoothly, very little queuing. This was our 1st time on Arcadia and I was very pleasantly surprised. She is a lovely mid sized ship and easy to navigate round. I was worried initially after reading some of the reviews but I can honestly say that this was the nicest ship I have sailed on with P&O. We had no problems which affected us. If I wanted to be really picky, then some of the lifts were out of use and some of the ladies toilets were also out of order, but there were plenty others around the ship to use. The food was plentiful and tastefully served in the Meridian restaurant, our waiters were very good and attentive. Arcadia has a wonderful 3 tier theatre with comfortable seating and the Headliners entertainment team were the best I have seen on any P&O ship yet. We have another cruise booked on this ship in December and can't wait. Oh and also went through the Bay of Biscay which I always dread and for the 1st time EVER, never felt any movement and didn't have to wear my sea bands. One very happy passenger!
