Transform your spectacular meeting or event vision into reality at The Westin Grande Sukhumvit, Bangkok. With 14 venues totaling over 1,725 square meters, the hotel provides the perfect setting and ideal location for productivity and focus. Outlined in elegant crown molding and awash in calming, neutral hues, the Grand Ballroom is ideal for conferences and grand affairs. Altitude, right at the top of the hotel on the 25th floor, is a private rooftop event space that is unique in the Sukhumvit area.
Clear thinking begins with Westin Clutter-Free Meetings, helping planners and guests stay focused with spacious rooms, essential amenities and invigorating SuperFoodsRx menu selections designed to fuel their productivity. Streamlined stations offer brainstorming staples such as paper, pens and refreshing beverages. Westin meetings also offer thoughtful “green” features such as energy-efficient light bulbs, double-sided meeting pads and water pitchers in lieu of bottles to help reduce waste.
At Westin, the team takes the time to understand your unique needs and will delight you with intuitive service, thoughtful touches, and enriching experiences, allowing you to enjoy each moment to the fullest.
Altitude comprises an indoor function space, an elegant breakout room for 20 called The Library, and an outdoor terrace for up to 50 guests, with a dramatic panorama of downtown Bangkok. Outfitted with ornate patterns, Thai influences, and bold pops of crimson, these picturesque spaces can accommodate up to 250 guests for a meeting or evening cocktail reception.
For smaller gatherings, Botan, which means "peony" in Japanese, can host up to 40 guests theater-style or be divided into up to four separate rooms for even more intimate occasions. Connected to Kisso Japanese Restaurant, it allows for working lunches or dinners-and also features a foyer area for coffee breaks.
Formal meetings can also be held in our eighth-floor meeting rooms, which share a pre-function area, or in our boardroom, which is bathed in natural light.
