Artemis was launched as Princess Cruises' extremely popular Royal Princess in 1984. Her godmother, the beloved Princess Diana, added an air of grace and style during her christening that remains undiminished. When introduced, the ship was a trail blazer -- the first ship built for the mainstream market to feature only outside cabins, each one with an ocean view. On board Artemis a view of the sea is never far from sight; not only do all cabins have a large window or balcony, there are an additional 16,000 square feet of windows. One of the most drastic changes the ship has undergone since joining the P&O fleet is that it is now an-adults-only vessel.
