Artemis is due for an extensive refit this month, with new furnishings, updated decor, replacement windows to enhance the views. They are also updating Trumps, the Coral dining room and Tiffany's. Starlights lounge, the Conservatory and the Horizon lounge are being newly redesigned. Cabins will have Egyptian cotton bed linens, slumberland posture sprung mattresses and newly refitted bathrooms. They are also providing pamper packs and the addition of a champagne breakfast menu. They are also increasing the number of therapies available in the spa. Sounds like luxury to me! I am sure you will enjoy it and I hope the above will set your mind at ease, have a wonderful time. Kind regard.
I suggest you look on the P&O site, Cruise Connections. Several people have posted comments about Artemis. I would say that the favourable comments outweigh some unfavourable ones. As it says in the previous answer the ship is due for a refit. Having been on Oriana after her refit I can say that I am sure Artemis will look fantastic.
