Capella

The “ultraluxury” hotel brand from Horst Schulze, former long-time president of Ritz-Carlton, arrives beside the Chao Phraya in the final quarter of 2018. The 101 suites come with sweeping river views, with Thai textiles and accents littered throughout the low-rise development. Within the property, you’ll find a riverside restaurant featuring input from Argentinian chef Mauro Colagreco, of the two-Michelin-starred Mirazur restaurant in Menton, France.

Edition

The arrival of Marriott’s boutique brand conceived by legendary hotelier Ian Schrager—the first guy to ever coin the phrase “boutique hotel”—has long been promised as part of the ultra-luxe MahaNakhon Tower development at Chong Nonsi. 2018 looks to be the year. There are only 10 other Edition hotels in the world right now, all glamorously well detailed and frighteningly expensive. For the rest of us there promises to be “five levels of public space.”
 

Four Seasons Hotel and Private Residences at Chao Phraya River 

Opening by the end of the year, the Four Seasons' return to Bangkok will include a hotel (300 rooms) and residences (350 all-corner units) in a 73-story building. The two projects, along with Capella (see above) are collectively being dubbed the Chao Phraya Estate, and will take up over 350 meters of river frontage and about 35 rai in total. 
 

Hyatt Regency

Thailand's fourth Hyatt will arrive in mid-2018 on Sukhumvit Soi 13, where it will enjoy direct sky bridge access to BTS Nana. The 273 rooms and suites will be decked out in a modern Thai style augmented by Hyatt’s usual elegant and sleek design. On-site, you’ll also find high-end shopping venues, two restaurants, a bar, fitness center and a spa.

Mandarin Oriental Residences at IconSiam

Set to open in late 2018, the mega B50-billion riverside development by three property giants—Siam Piwat, Magnolia Quality Development and Charoen Pokphand—will transform an 80,000-sq-meter plot of land on Charoen Nakhon Road into something approaching a brand new suburb. It will consist of the Mandarin Oriental Residences (two luxurious skyscraper and condominiums, 70 and 52 floors), 100-plus restaurants, a 3,500-seat auditorium, a “Heritage Museum” and the giant Takashimaya mall from Japan.

 

Waldorf Astoria

First slated to open in 2015, Waldorf Astoria is really, truly opening in the second quarter, 2018. It’ll be the first incursion of the Hilton’s luxury hotel brand into Southeast Asia. Perched nearby the Royal Bangkok Sports Club and Ratchaprasong Intersection, the hotel features interiors by architect Andre Fu. The 171 rooms and suites—including some of the largest in downtown Bangkok at 300sq meters—each feature floor-to-ceiling windows. There will be six high-end F&B outlets, including a 55th-floor rooftop bar decked out by local firm AvroKo. 

Koh Samui

Holiday Inn Resort and Express Samui Bophut

The northern coast of Samui will welcome two iterations of the no-frills Holiday Inn chain this year: a 150-room “Resort” and a more affordable, 200-room “Express” hotel (both opening in late 2018). Both are situated close to Fisherman's Village, alongside Bophut Beach, only a short walk away from the walking street and entertaining hub. ihg.com/holidayinnexpress

Ibis Styles Samui Chaweng Beach

The colorful, affordable hotel chain’s latest opening (scheduled for late ’18) will feature 129 rooms, a rooftop bar, a market-style restaurant and a location in stumbling distance of Hard Rock Cafe and Central Festival Samui. You know your stay will be far from quiet, but the upside is you’re only a short walk away from the night street. ibisstyleskohsamuichawengbeach.com

Park Hyatt Phuket

Set to open by 2018, Park Hyatt Phuket’s 201 rooms boast private balconies with stunning views of Kamala Cove and facilities befitting a five-star hotel. The resort sits on the slow-paced Kamala Beach, which still remains somewhat underrated, so you’ll get to relax without the bustling tourist crowds. phuket.regency.hyatt.com

W Retreat Phang Nga Bay

Situated on Koh Yao Noi, a small island set in the middle of Phang Nga Bay, Thailand’s 2nd W Retreat is a 30-minute speedboat ride from Phuket. The 79 villas each come with private plunge pools overlooking the sandy white beach and turquoise waters rich with coral. It’s not all lazing in the sun, though—this island is especially known for its diving, snorkeling and rock climbing. Scheduled to open in Jan, 2018.
