I'm going to Bangkok for a medical procedure next month. Please suggest a suitable 5 star hotel away from possible disruptions caused by unrest.
It depends on whether you want to be close to your medical care facility.
5-star hotels are clustered only in a few areas. I'll use the BTS station names so you can easily visualize on a map.
Saphan Taksin BTS (River)
6 choices: Peninsula and Hilton Millenium across on the Thonburi side, Shangri-la, Oriental and Royal Orchid Sheraton on the "right" side i.e. do not need to cross the bridge and Anantara far down south on the other side.
Pros: No protests camped out there. Good for temples.
Cons: Further away from city center
Saladaeng BTS (Silom/Sathorn)
Choices: Le Meridien, Banyan Tree, Dusit and Lebua
Pros: Entertainment district
Cons: Protesters camped out at Lumpini. Flashpoint at last protest. Relatively lousy hotels.
Siam BTS (Pathumwan)
Choices: Kempinski
Pros: Shopping ground zero: Paragon Mall, Siam Sq, MBK + Chula U co-eds.
Cons: Relatively near protestors but far away enough. Little to no 5-star hotels
Chidlom BTS (Ratchaprasong)
Choices: Ground-zero for 5-star hotels: Grand Hyatt Erawan, Intercontinental, Renaissance, Centara, Ritz Carlton, Okura etc.
Pros: Throw a stone in any direction and you'll hit a 5-star direction. Close to great shopping: Central World, Pratunam.
Cons: Ground-zero for protestors in the city center area. Stage is right at Central World. Grenade attack couple of days ago.
Phloenchit BTS ("lower" Sukhumvit)
Choices: JW Marriott, Conrad, Plaza Athenee
Pros: Nana around the corner. Bumrungrad hospital too. A little further from protests.
Cons: Nana around the corner.
Asoke BTS (Sukhumvit)
Choices: W and Sheraton Grande Sukhumvit are directly connected to BTS.
Pros: Terminal 21 mall. Soi Cowboy. Koreantown
Cons: Protestors have a stage here too.
Phrompong BTS (Sukhumvit/Thonglor)
Choices: Hilton Sukhumvit, Marriott Sukhumvit
Pros: Emporium Mall. Farther away from protestors. If you have to escape to Pattaya, the Ekkamai bus station is 2 stops down.
Cons: At the relative edge of city center.
There you have it. Little to no 5-star hotels in other areas. 5-star service but no 5-star hotels in Ratchada unfortunately.
