"Leading with Luxury
With a continued focus on creating unique, transformative, and culturally immersive experiences, The Ritz-Carlton brand is set to debut in Bangkok in 2024 with the opening of The Ritz-Carlton Bangkok. Occupying the first 24 floors of a 50-storey tower in the upcoming One Bangkok mixed-use development on the prestigious Wireless Road, the hotel will blend the brand’s legendary service with the best of Thai hospitality, design, culture, and cuisine."
