Event spaces
The venue lists these spaces. Capacities are the venue’s own figures and change with the layout you choose.

- Islandview
- Tobin
- Boardroom
- The Rosseau
- Windermere Pub
- The Waterfront Green Space
- Verandah (outdoor)
Capacity
The venue publishes a maximum of 120 seated, 130 standing reception. 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 private social events.

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.
