Studio 1

The property features the Grand Ballroom, one of Mumbai's most capacious hotel ballrooms, supported by multiple breakout meeting rooms including the Sahar Rooms and dedicated pre-function foyers. Each space can be configured for theatre, banquet, classroom, or cocktail formats. Spalba's listing for JW Marriott Mumbai Sahar includes floor plan references to help planners compare setup options side by side.

The hotel offers outdoor terrace and poolside areas that can be set up for cocktail receptions and pre-wedding functions. These spaces complement the indoor ballroom for multi-function wedding formats. Availability and capacity for outdoor setups depend on season and event date. Enquiring through Spalba allows planners to check current outdoor space availability alongside indoor ballroom bookings.

As a full-service luxury hotel and established Mumbai banquet venue, JW Marriott Mumbai Sahar operates an in-house culinary team offering multi-cuisine menus spanning Indian, Continental, and Asian formats. Vegetarian, Jain, and customised dietary menus are available. The property follows a managed in-house catering model; external food vendors are not permitted. Beverage and bar packages are available subject to event type and applicable regulations.

The hotel's event spaces are equipped with professional audio-visual systems, including projection screens, PA systems, and high-speed Wi-Fi connectivity.

Planners requiring specialist AV setups such as LED walls or live-streaming rigs can coordinate additional requirements through the hotel's event services team at the time of booking.

JW Marriott Mumbai Sahar houses over 580 guest rooms and suites, making it well-suited for multi-day conferences, destination weddings, and MICE programmes where outstation delegates require on-site accommodation. Room block arrangements for event groups can be negotiated directly with the hotel. Spalba's enquiry feature lets planners raise accommodation block requirements alongside their event space query in a single submission.

Situated in Sahar, the hotel is approximately 1 to 2 kilometres from Chhatrapati Shivaji Maharaj International Airport, making it the closest five-star hotel to Mumbai's international terminal. This proximity is a key logistical advantage for airport-adjacent MICE events and for guests flying in from other cities. The short transfer time reduces delegate fatigue and simplifies ground transport planning significantly.

The property offers valet parking services for event guests. Given its airport-adjacent location in Sahar, many outstation guests arrive directly from the terminal, reducing private vehicle volumes. Planners organising large events should coordinate with the hotel's event team regarding dedicated parking bays and valet deployment timelines to ensure smooth guest arrival and departure flows on the event day.

The hotel is designed to international JW Marriott brand accessibility standards, with lift access to all event floors, ramp access at key entry points, and accessible washroom facilities. Event planners coordinating attendance for differently-abled guests are advised to confirm specific room and route requirements with the hotel's events team prior to the event date to arrange appropriate assistance and seating configurations.

For large-format events such as gala dinners, corporate conferences, and weddings at this high-demand Mumbai airport hotel, booking 6 to 12 months in advance is strongly recommended, particularly for peak season dates between October and February. The Grand Ballroom is one of the most sought-after event spaces in the Sahar corridor. Raising an enquiry through Spalba allows planners to check real-time availability quickly.

Once an enquiry is submitted via the Spalba listing, the property's sales and events team receives the brief and typically responds with availability, preliminary pricing, and package options. Spalba's platform records the conversation thread, keeping all communication in one place. Planners can use Spalba's enquiry form to specify guest count, event date, setup preference, and accommodation requirements in a single structured submission.

The hotel offers event packages structured around per-plate food and beverage rates alongside venue rental components, which vary by event type, day of week, and season. Exact pricing is shared during the quotation stage following an enquiry. Planners are encouraged to request itemised quotes covering catering, AV, décor services, and room blocks to allow accurate budgeting before signing a booking agreement.

As a flagship luxury wedding hotel in Mumbai's airport district, JW Marriott Mumbai Sahar supports multi-function wedding formats including mehendi, sangeet, ceremony, and reception events across its ballroom and outdoor spaces.

The hotel's event infrastructure supports multi-day MICE programmes with a primary plenary hall and several breakout meeting rooms that can run concurrent sessions.
