I stayed in a $780-per-night cruise stateroom on a new ultra-luxury ship. I now understand why wealthy travelers like cruises.

The cruise line hosted me on the new Seven Seas Grandeur during its three-night non-revenue "christening" sailing.

However, I did have some issues with the floating hotel room. But before we get there, let's see how the cruise line can charge so much for a floating room.

I previously spent one night in premium cruise line Oceania Vista's veranda stateroom and Explora I's ocean terrace suite. The latter, owned by MSC Group, is a newcomer to the luxury cruise industry.

But at 322 square-feet with an additional 83- to 132-square-foot balcony, this cabin is one of the largest I've stayed in.

The balcony was shockingly large, enough to accommodate two lounge chairs and a small table without feeling cramped.

Unlike most cruise cabins, the king bed faced the windows instead of another wall, making the bed "room" feel more spacious than usual.

The television, which could swivel to face the bed, was mounted on a console-like bar equipped with drawers, glassware, and a small plate of fruit.

This one came with an Illy-stocked espresso machine, a mini-refrigerator with sodas, and bottles of drinking water.

The center of the room was left open and furniture-less.

Besides appreciating it, I had no idea what to do with this extra space.

This tabletop extended down the hall and served as my dumping ground for grab-and-go items like my phone and camera.

Drawers, shelves, and several rows of hangers lined this narrow room.

To my surprise, my less expensive ocean terrace suite on the Explora I had a wider walk-in closet than this.

I could've moved my entire wardrobe into this closet and still have space to spare. Just don't ask me to stand in there for too long — it's a bit claustrophobia-inducing.

The marble and stone detailing made it feel as plush as a bathroom I'd expect in a five-star hotel.

Unexpected luxuries like the double vanity, bathtub, and multiple towel hangers made this one of the most luxurious bathrooms I've had both at sea and on land.

The attention to detail — like the reading light-lined couch, swivel TV, and fresh fruit plate — were all small but wonderful additions.

While I didn't touch the latter, I did find a few strawberry leaves in my bathroom after housecleaning came by. At least the fruits weren't going to waste, right?

It seemed the designers prioritized the large living room over a comfortable closet, a fair choice.

If you had told me that this ship was a few years old, I would have believed you.

But the grey and tan color scheme with muddy blue accents looked more like a high-end but old hotel than a sleek and modern ship.

In 2024, the concierge suite starts at $5,455 per person for a seven-night December cruise roundtrip from Miami, Florida to Mexico, Belize, and Honduras.

This price then ranges up to $20,200 for the 14-night roundtrip cruise in April from Barcelona, Spain to France, Monaco, Italy, Malta, and other Spanish cities.

Regent Seven Seas is all-inclusive. No need to pay extra for excursions, flights to and from the ship, and unlimited drinks and food.

And in terms of amenities, it's hard to top a cabin like this.

But I've never had amenities like a double vanity or bathtub in a cruise cabin before.

If I, a public cruise skeptic, was convinced by these little luxuries, I'm sure any other cruise cynic would be as well.

If it's within your budget, this could be a good option. The small walk-in closet left me a little claustrophobic, and I didn't love the somewhat dated interior design.

But that could probably be overlooked — especially given the other luxuries, like that huge balcony.

And I'm sure you'll agree after lounging in a warm bubble bath in the suite's marble-lined bathroom.
