Sukhumvit Grand Ballroom & Sukhumvit View

This modular configuration is particularly useful for multi-track conferences and phased wedding receptions. Contact the hotel's event team via Spalba to confirm the exact partition configurations available on preferred dates.

The hotel has terrace and pool deck areas that can be used for cocktail receptions and social gatherings, subject to weather conditions and availability. Bangkok's tropical climate means outdoor events are generally best scheduled between November and February. The hotel's event coordination team can advise on contingency indoor setups to ensure events proceed smoothly regardless of weather.
