Grand Ballroom

The Grand Ballroom can be partitioned into three independent sections, each with its own dedicated entrance and audiovisual infrastructure. This flexibility allows simultaneous conferences, gala dinners, and cocktail receptions to run without interference. Each subdivided section connects to pre-function foyer space suitable for registration, exhibition displays, or welcome cocktail setups, giving planners precise control over flow and atmosphere.

The property includes outdoor terraces and poolside areas available for private cocktail receptions and social gatherings. Bangkok's climate makes covered or partially sheltered outdoor setups the recommended format; the hotel's event team advises planners on weatherproofing solutions including canopy and tent arrangements. Exact outdoor capacities and layout options are confirmed during the site visit coordinated through a Spalba enquiry.

Grand Hyatt Erawan Bangkok operates fully in-house catering across all event formats, a hallmark of luxury MICE hotel catering in Bangkok. The culinary team delivers Thai, Chinese, Japanese, Italian, and international buffet menus, with customised plated and family-style options available. Vegetarian, vegan, halal, and allergy-specific menus are accommodated upon advance request. Alcohol is served and beverage packages are structured per event requirements.

All function rooms are equipped with built-in LED screens, high-definition projectors, professional PA systems, and adjustable stage lighting. The hotel provides a dedicated on-site technical crew for setup, live support, and breakdown. High-speed Wi-Fi covers all event floors with dedicated bandwidth options for large delegate groups. Hybrid and live-streaming configurations are supported for international conferences and virtual-attendance MICE events.

Grand Hyatt Erawan Bangkok offers 380 rooms and suites, including Club rooms with access to the Grand Club Lounge. Room block arrangements for conference and wedding groups are coordinated by the hotel's events team, with preferential group rates available when booked in conjunction with a function. The property's central location makes it equally convenient for outstation delegates staying elsewhere nearby.

Grand Hyatt Erawan Bangkok sits in the Ratchadamri–Lumphini corridor of central Bangkok, a key business district event location. Suvarnabhumi International Airport is approximately 30 kilometres away, translating to 45 to 60 minutes by road depending on traffic. BTS Chidlom station connects via a covered skywalk to the adjacent CentralWorld complex, placing the hotel within a two-minute walk of direct BTS Skytrain access.

Valet parking is available at the hotel's main entrance on Ratchadamri Road. Self-parking is accessible in the adjacent multi-storey car park shared with the Erawan Bangkok complex. For large-scale events, the events team pre-coordinates dedicated parking allocations and valet lanes. Planners are advised to confirm total vehicle estimates with the venue team so adequate ground-floor arrival management can be arranged.

The property is fully accessible, with step-free entrances, dedicated lifts serving all event floors, accessible restrooms on each function level, and designated drop-off points at the main porch. Wheelchair-accessible seating can be incorporated into any theatre, banquet, or classroom layout upon advance notice. The hotel's accessibility arrangements meet international hotel brand standards and can be reviewed in detail through a pre-event site inspection.

For the Grand Ballroom and multi-day MICE conferences, a booking lead time of six to twelve months is strongly recommended, especially for peak Bangkok event seasons between October and February. Spalba's direct enquiry tool for Grand Hyatt Erawan Bangkok connects planners with the venue's dedicated event sales team without intermediary delays, allowing faster date confirmation and proposal turnaround for corporate event booking in Bangkok's premium hotel segment.

Cancellation and deposit terms are detailed in the event contract issued by the hotel's sales team and vary based on event size, season, and the scope of services confirmed. A signed contract with a deposit typically secures the function date. Planners are advised to request the full terms during the proposal stage, as policies for peak-season dates differ from off-peak bookings.

Grand Hyatt Erawan Bangkok permits approved external decorators, florists, and entertainment vendors to work within its event spaces, subject to prior approval by the hotel's event management team. Vendors must comply with load-in schedules, insurance requirements, and on-property guidelines. The hotel's in-house décor coordination team can also manage complete floral and setup arrangements for clients who prefer a single point of contact.

The hotel provides a dedicated wedding specialist who manages end-to-end planning for luxury Bangkok hotel weddings, covering floral design, bespoke menu creation, entertainment curation, and pre-wedding ceremonies. The Grand Ballroom is equipped with a bridal holding suite and staging infrastructure suited to both Western and traditional Thai ceremony formats. Spalba's listing for the property includes direct enquiry access to initiate a wedding consultation.

The hotel offers structured MICE packages covering day-delegate rates, full-delegate rates with accommodation, and customised corporate packages for multi-day conferences. Packages typically include coffee breaks, lunch, AV equipment, and dedicated event coordinator support. The meeting floor's configuration of breakout rooms alongside the Grand Ballroom supports plenary-and-workshop formats with up to 2,000 delegates in the main hall and concurrent breakout capacity across adjoining rooms.

Grand Hyatt Erawan Bangkok issues VAT-compliant tax invoices in accordance with Thai Revenue Department regulations, with 7% VAT applied to all applicable services. Corporate accounts and direct billing arrangements are available for qualified companies, subject to a credit application process initiated through the hotel's finance team. Detailed invoice breakdowns covering venue rental, catering, AV, and accommodation can be structured to meet corporate procurement and reimbursement requirements.
