The Park Hyatt Bangkok opened in 2017. I had a pleasant stay there late last year. I combined a paid stay with a free night Hyatt credit card holders receive annually. While this hotel is new and luxurious with many nice features, there are also some attributes that I found to be less than impressive compared to stays at other Park Hyatts such as the Park Hyatt Hadahaa in the Maldives and the Park Hyatt Saigon.
Location
Plus: The hotel is conveniently located on Sukhumvit Road near the Phloen Chit Skytrain station in Bangkok’s prime tourist/shopping district. The hotel is part of the Central Embassy Shopping complex.
Minus: The entrance to the hotel on the street level is merely a bank of elevators. The “lobby” is just a small check-in area on the 10th floor.
In my view, an urban, luxury hotel should have a large welcoming lobby similar to the lobby of the Grand Hyatt Erawan Bangkok. From the street, the Park Hyatt is practically invisible.
Rooms
The Park Hyatt has 222 rooms and 32 suites. I was assigned a beautiful standard room with a king-sized bed. The room was as large as a suite. Standard rooms range in size from 48 to 63 square meters. I estimate that my room was in the lower portion of that range. Like the rest of the hotel, the design of the rooms is contemporary.
Entry Hall
The entry has the bath one one side and a gigantic walk-in closet on the other.
Bath
The marble bath is large with a walk-in shower on one end and soaking tub on the other.
The double vanity is located between the shower and tub.
The bath is stocked with amenities like dental and shaving kits, hair dryer, nail file, cotton buds, etc. Additional personal grooming items are available upon request. 
Le Labo provides bathing supplies.
Walk-in Closet
The roomy closet includes plenty of room to hang clothes or store them folded as well as room for luggage, a safe, ironing board and iron, and robes and slippers.
Bedroom
The key features of the bedroom are the floor-to-ceiling windows, the king-sized bed, and the 55-inch TV.
The room also has a minibar, coffee maker, and electrical outlets near the bed. I had no complaints about the WiFi.
Plus: The size of the room, windows and TVs are some of the largest in Bangkok for a standard room.
Minus: The contemporary design was a little to harsh for my preference.
Breakfast Buffet
The hotel offers a very good breakfast buffet in the Embassy Room overlooking the pool. As a Hyatt Globalist, the buffet was free.
Additional items are available in the Pantry next to the Embassy Room.
Plus: Good food and views.
Minus: Using two rooms for the buffet is a little inconvenient.
Pool
A unique feature of this hotel is the saltwater infinity pool.
Plus: Great views.
Minus: Some may not like the saltwater.
Lounge
Hyatt Globalists and Explorists, the top two levels in its frequent guest program can have evening cocktails and snacks in The Bar.
A waitress serves an assortment of snacks and beverages.
Plus: The snacks are very good and substantial enough to pass for a meal.
Minus: None really.
Other Areas
To compensate for the lack of a lobby, the hotel has some smaller rooms that are available for reading or quiet conversation with visitors.
Plus: It is good that the hotel provides space to offset the lack of lobby.
Minus: No lobby.
Overall Impression
The Park Hyatt Bangkok is very nice urban hotel in a great location in one of the the world’s best cities for tourists. I think its best features are the huge rooms and its location. A Park Hyatt, though, deserves a lager lobby and common areas than those in this hotel. My preference is for a hotel that evokes feelings of a comfortable residence. The Park Hyatt Bangkok felt more like a modern office building.
