Having read many reviews of this ship, we came on to it with an open mind. Child free..yes..but the downside is the adult age profile is much higher than anticipated. But older people feel very safe on this ship. Food not so brilliant. My wife is a non-meat eater and likes pasta dishes. But they were few and far between. The Meridian kitchens seem too far from the tables, and the food was never really hot by the time it had arrived, and been served to all on our table.
The evening entertainment was good, but not up to standards of Royal Caribbean or Princess Cruises. Became very "samey" after a few nights, with in-house Headliners trying their beat to perform different styles of music & dance from different eras, but not quite achieving.
Port & shore excursions were very well organised with good content. Our cabin (outside with restricted view) was excellent, and was the service from our cabin attendant.
The Arcadia decor needs livening up. Very staid, dark, with majority being a dark wood look (mahogany??). Needs a brighter image, but again probably suits age profile.
The big advantage of Arcadia was the price of drinks !!! Sometimes lower than pubs and bars in UK cities, and the bar service was always first class.
Plenty of sun loungers and seats in quiet areas, and plenty of alternative activities on board on sea days. The big negative, though, was the size of the viewing theater for films, especially on sea days. Only 30 seats, and many passengers could not see the films, although they were shown over half dozen times per day. Needed to be in the large Palladium Theater a couple of times per day. At least over 500 could then watch in one go !!
So generally, if you want a bright, vibrant ship, Arcadia is not for you. If you want total peace and quiet, and your age profile is suited to a really slow pace, then OK.
Embarkation and disembarkation first class !!
But I feel we will always go to Royal Caribbean and Princess first, unless somebody can tell me that the other P&O ships offer a lot more than Arcadia....and they probably do!!
