Alpha Square

The hotel offers several dedicated event venues including the Siam Ballroom, which is its primary large-format space, along with a range of smaller meeting rooms suited to breakout sessions, boardroom meetings, and private dining. Each space supports multiple setup formats including theatre, classroom, banquet, and cocktail arrangements to suit different event requirements.

The property primarily features indoor air-conditioned event spaces, which is well suited to Bangkok's tropical climate. Indoor venues at this Pathum Wan hotel are designed to handle large-scale banquets and conferences without exposure to seasonal rain or heat. Planners seeking outdoor alternatives on the Spalba platform can filter nearby properties with dedicated outdoor or rooftop options.

The hotel operates an in-house catering team offering international and Thai cuisine across set menus and bespoke banquet packages. As an Accor-affiliated property, food quality and service standards follow the Novotel brand's hotel catering guidelines. Vegetarian menu options are available, and the culinary team can accommodate specific dietary requirements when requested during the planning phase.

The hotel's event spaces are equipped with built-in AV systems including projectors, screens, and PA systems supported by an on-site technical crew. High-speed Wi-Fi connectivity is available across event floors, which is essential for hybrid conferences and corporate presentations. Planners requiring additional specialist AV equipment can discuss third-party supplier arrangements with the hotel's events team.

The property offers over 400 guest rooms and suites, providing substantial on-site accommodation for conference delegates, wedding guests, and corporate groups attending multi-day events. Room block arrangements can be negotiated directly with the hotel's group reservations desk, which is advisable for events drawing outstation or international attendees requiring guaranteed room availability.

Suvarnabhumi International Airport is approximately 30 to 35 kilometres from Siam Square, with travel time typically ranging between 40 and 60 minutes depending on traffic conditions. The hotel's central Bangkok location for MICE events is further strengthened by its direct connection to Siam BTS Skytrain Station, making it accessible from the airport via the Airport Rail Link and a BTS transfer.

The hotel is directly connected to Siam BTS Skytrain Station, one of Bangkok's primary interchange points on the Sukhumvit and Silom lines. This makes it exceptionally convenient for delegates arriving from across the city without relying on road transport. The covered walkway access eliminates weather-related inconvenience, a practical advantage for morning conference starts and evening gala dinners.

The hotel offers parking facilities for guests arriving by private vehicle, with valet and self-parking options available. Given the property's location within the central Siam Square commercial district, planners coordinating large events are advised to confirm parking capacity with the hotel events team in advance, particularly for events where a significant proportion of guests are expected to drive.

The Spalba listing for Novotel Bangkok on Siam Square allows event planners to submit a direct enquiry specifying event type, expected guest count, preferred dates, and catering requirements. This Bangkok hotel event booking process connects planners directly with the property's MICE and events team, enabling a faster response compared to generic hotel contact forms. Virtual walkthrough features may also be available on the listing.

For large-scale conferences or events requiring the Siam Ballroom, bookings are advisable at least three to six months in advance, particularly during Bangkok's peak MICE season from October through February. Smaller meeting rooms may be available on shorter notice. Early enquiry through Spalba helps secure preferred dates and allows adequate time for customised catering and AV planning.

Cancellation and rescheduling terms are governed by the hotel's event contract, which varies based on event size, advance notice given, and whether a deposit has been placed. Planners are strongly advised to review the specific cancellation clauses within the formal event agreement before signing. Detailed policy terms can be requested directly from the hotel's events team during the enquiry stage.

The hotel provides wedding planning support through its dedicated events team, which assists with banquet configuration, menu planning, décor coordination, and accommodation arrangements for bridal parties and outstation guests. As a Siam Square luxury hotel wedding venue, it offers the advantage of a central location with strong transport links, allowing guests from across Bangkok to attend without logistical difficulty.

Multi-day corporate conferences are well supported at the property, which combines a substantial main ballroom with adjacent breakout meeting rooms, on-site accommodation exceeding 400 rooms, and in-house catering for all-day dining requirements. The hotel's events team coordinates plenary sessions, breakout tracks, and networking dinners under a single venue arrangement, reducing coordination complexity for corporate planners managing large delegations.

As a formally registered hospitality property operating under Thailand's standard tax framework, Novotel Bangkok on Siam Square issues official tax invoices for event and accommodation charges, which corporate clients require for expense reporting and reimbursement. Planners managing cross-border or regional corporate events should confirm specific invoice formats and VAT documentation requirements with the hotel's accounts or events team at the time of booking.
