Anantara Siam Bangkok Hotel has 354 rooms and suites, including Grand Deluxe Rooms, Junior Suites, and signature Anantara Suites.

Situated on Rajdamri Road in the Lumphini district of Pathum Wan, the hotel is a strategically accessible Bangkok MICE hotel for domestic and international delegates. Suvarnabhumi International Airport is approximately 30 kilometres away, with a typical transfer time of 40 to 60 minutes depending on traffic. Don Mueang Airport is roughly 25 kilometres north. The property is within minutes of the BTS Skytrain Ratchadamri station.

BTS Skytrain Ratchadamri station on the Silom Line is the nearest public transit stop, located approximately 300 metres from the hotel entrance. BTS Siam station, a major interchange, is also within comfortable walking distance. These connections make the property easily reachable for guests travelling from all parts of Bangkok without relying on private vehicles or taxis.

The hotel provides valet parking services for event guests and has on-site parking available. Complimentary or validated parking arrangements for large group events can be discussed with the events team at the time of booking. Given the central Pathum Wan location, guests arriving via BTS Skytrain or private car transfers from major hotels and residences across Bangkok will find access straightforward.

For high-capacity banquet hall bookings in Bangkok's competitive luxury hotel segment, the Grand Ballroom and Siam Ballroom typically book out several months in advance, especially during peak wedding and conference seasons from November through February. Corporate planners targeting these months are advised to submit an enquiry on Spalba at least six months ahead. Spalba's direct enquiry tool connects planners with the hotel's events team without intermediary delays.

Specific cancellation terms and deposit requirements are confirmed in the event contract issued after initial discussions with the hotel's events team. Policies vary based on event size, lead time, and whether accommodation blocks are included. Planners are advised to review these terms carefully before signing. Submitting an enquiry through Spalba initiates an official conversation with the hotel team who will outline all applicable terms.

The hotel assigns a dedicated events coordinator to each confirmed booking. For multi-day MICE programmes, this coordinator manages room configurations, catering scheduling, AV requirements, and delegate rooming lists throughout the planning process. This single-point-of-contact model reduces coordination complexity for corporate organisers running conferences, training programmes, or annual general meetings that span two or more consecutive days at the property.

Anantara Siam Bangkok Hotel is an established destination wedding hotel in Bangkok's Pathum Wan district, offering tailored Thai and international ceremony packages.

Couples can initiate the planning conversation via the hotel's Spalba listing enquiry page.

The hotel's suite inventory includes spacious Anantara Suites that are commonly reserved as bridal preparation and accommodation suites for wedding couples. These suites offer generous living areas, in-room spa services, and direct access to the hotel's butler service, supporting a comfortable pre-ceremony preparation experience. Specific suite assignment and wedding night arrangements can be discussed as part of the overall wedding package negotiation.

As an internationally managed hotel operating under Thai tax regulations, Anantara Siam Bangkok Hotel issues formal tax invoices compliant with Thai VAT requirements, including 7 percent VAT applicable on event services. Corporate clients can request official receipts and invoice documentation suitable for company expense reporting and reimbursement processes. International organisations requiring specific billing formats should discuss requirements with the hotel's finance and events team during the contracting stage.
