Capacity

The venue publishes a maximum of 450 seated, 504 standing reception, 504 theatre style. Those are top figures for an empty room. A dance floor, a stage, a buffet or a photo booth each take space, so plan on fewer guests than the maximum once your layout is drawn.

A useful rule: a seated dinner at rounds of ten needs about 1 to 1.2 square metres per guest, a standing reception about 0.7, and theatre seating about 0.6, before you add a stage or dance floor. The venue capacity calculator does the arithmetic for your room.

Events it hosts

According to its own event pages, the venue hosts weddings, corporate events and conferences and meetings.

For timelines, budgets and checklists, start with the wedding planning hub, corporate holiday party hub, conference planning hub.

Planning entertainment here

Hotel ballrooms usually have the power and access for stage acts, but ceilings and rigging vary from room to room. Ask for the ceiling height under any chandeliers, and check whether in-house audio-visual must be used for performers.

Send every performer’s technical needs to the venue before you book: floor space, ceiling height, power, sound and changing room.

Getting there

Check the venue website for directions, parking rates and accessible entrances, and send the details to guests with the invitation.
