(CNN) — Whether it's an island escape or an urban destination, the world's top hotels are tailoring their treats to suit ever more discerning travelers. As the most exclusive resorts go to even greater lengths to differentiate their offerings, we pack up the designer luggage to find the best new properties where you can stay in 2017 (and beyond):
1. Soneva Jani, Maldives
With 24 over-water villas and one sprawling island villa set on a private lagoon in the Maldives, the newest Soneva resort might just be the best yet.
Each of the resort's multilevel water villas has its own private pool and a retractable roof that allows guests to sleep beneath the stars. Many villas also have slides that transport guests directly from the top level into the lagoon below. Other hotel highlights include a spa, an observatory -- home to the largest telescope in the Indian Ocean -- and an outdoor cinema.

Its 22 accommodation units include five luxury tents with wraparound decks and private dining areas.

The 159-room hotel is home to a 500-stable polo academy, show-jumping and dressage arenas, and a riding school. Adults and children are invited to interact with the horses stabled at the property's polo fields.

After a year of extensive renovations, the 125-year-old Hotel Eden -- a favorite of director Federico Fellini -- will finally open its doors as a Dorchester Collection hotel.
Rooms have been reduced from 121 to just 98, and have been beautifully redesigned with a more modern and understated feel. There are a few new additions to look forward to, including a casual all-day brasserie and a hidden library bar. But the restaurant's iconic La Terrazza restaurant -- and its jaw-dropping views over the Eternal City -- still remain.

10. Assila Hotel, a Rocco Forte Hotel, Jeddah, Saudi Arabia
Rocco Forte's 10th hotel -- and its first foray into the Middle East -- does not disappoint. It's playful and modern, with 147 rooms and 63 suites offering panoramic city views (it's possible to see the Red Sea from some suites).
There's a rooftop pool and four excellent restaurants, the standout being Aubergine, which serves Arab and Mediterranean fare. Added bonus: It's in the heart of Jeddah's business district, close to Jeddah Mall and just 40 minutes' drive from Mecca.

Its 89 bedrooms and 11 suites are sleek and modern, while common areas are classically decorated with Corinthian columns, ornate plasterwork and crystal chandeliers.

The Waldorf Astoria's first West Coast property is fabulously over-the-top -- not that you'd expect any less from the ritzy hotel group. Tucked in the heart of Beverly Hills, California, the 12-story Art Deco hotel will feature a 5,000 square foot spa by La Prairie and a restaurant by Michelin-star chef Jean-Georges Vongerichten.
There are 170 rooms and 51 suites, three of which have private plunge pools. According to the hotel, every room in the hotel will have unobstructed views over the city of Los Angeles.
13. The Fontenay Hamburg, Hamburg, Germany
Set on the tranquil banks of Lake Alster, The Fontenay will be the first new luxury hotel in Hamburg, Germany, in 18 years. It was designed by local architect Jan Stormer to mirror the fluid lines of the lake and surrounding parkland, and reportedly cost more than $100 million to build.
Each of its 131 rooms and suites feature a private balcony and floor-to-ceiling windows with Lake Alster views. The property, which is already a member of the Leading Hotels of the World, will also offer a 10,000-square-foot spa with an indoor-outdoor infinity pool.
14. SLS Brickell, Miami
Starck style: the SLS Brickell is Miami at its best

This new Philippe Starck-designed hotel isn't your typical Miami Beach hotel.
For one, it's not on Miami Beach, but in the nearby neighborhood of Brickell -- an up-and-coming area filling up quickly with bars, restaurants and museums. Unlike its flashy, beachfront counterparts, the SLS is understatedly stylish rather than painfully hip.
Its 124 rooms feature clean lines, subdued color palettes and a minimalist aesthetic. The hotel's pièce de résistance? A rooftop deck with an infinity pool and views over downtown Miami.
