Here’s a curated list of Dubai hotels known for private event hosting (ballrooms, private beaches/villas, boardrooms, terraces, exclusive restaurant buyouts, etc.), with a short note on the kinds of private spaces and typical max capacities or standout features. I included the hotel event pages/supplier listings so you can view floor plans, capacities and contact their events teams.

Notes and next steps

• All these hotels publish detailed meeting/event pages (floor plans, capacities, AV services and contact emails) — I cited each hotel’s events/meetings page above so you can check exact capacities, menus and availability. If you want, I can:
  • Filter this list by guest count (e.g., 20, 100, 500), budget level (luxury vs. mid‑luxury), or location (Downtown vs. Palm vs. JBR).
  • Draft a short inquiry email to the events teams (I’ll include guest count, preferred date range, event type and any special requests) that you can send directly.

Which filter would you like me to apply (guest count, date, budget or event type), or would you like me to draft inquiry messages for a few of these hotels?
