The latest push into high-end travel is taking place on the high seas, as cruise lines increasingly lean on luxury offerings.
On Regent's Seven Seas Splendor, an all-luxury ship, cabins cost anywhere from $1,800 to $15,000 per night for its top-of-the-line booking, the Regent Suite.
The difference is not just the roughly 5,100 square feet of space. The top-tier suite has a Steinway piano, a private dining room and a wraparound deck with a hot tub and a view comparable to the one from the ship's bridge.
Multiple passengers wanted the suite for the Splendor’s 151-night global cruise that embarks in January, Regent told CNBC, and it is almost always occupied.
Regent is setting its sights even higher, as the cruise line plans to debut the Seven Seas Prestige in December, its first new ship class in a decade. Its top suite will cost $25,000 per night.
