AV, setup and service basics
Specific AV inventory (projectors, screens, microphones, staging) is not listed in the dossier; planners should request an up-to-date AV and rigging package from the W Las Vegas events team. The property provides in-house banquet and wedding services and coordinates food-and-beverage for private functions.
When you confirm a booking, ask about room turnaround times, preferred vendors (if any), and whether there are any limits on ceiling rigging or outside AV suppliers. Also verify whether meeting-room Wi‑Fi is included with your contract — guest rooms booked direct typically include in-room Wi‑Fi for Marriott Bonvoy members.
- Request current AV and rigging specs from hotel events/banquet manager
- Confirm F&B minimums and whether 3940 Coffee and Tea, Living Room or Skyfall can provide event catering or pre/post-event receptions
- Verify Wi‑Fi terms for meeting rooms as part of the contract
| Service | Planner action |
|---|---|
| AV inventory | Request the hotel’s AV packet and pricing |
| F&B and catering | Ask events team for sample menus and banquet minimums |
| Internet | Confirm meeting-room Wi‑Fi speeds and charges |
