Quick guide — which to pick

• Small meetings / boardroom (≤50): Grosvenor House, Conrad Dubai, JW Marriott Marquis (boardroom suites). (marriott.com)

Short checklist when choosing a hotel for a conference

• Required capacity (plenary + breakouts + exhibition footprint).
• AV/technical capability (LED screens, simultaneous interpretation, internet bandwidth).
• Location: proximity to Dubai International Airport, DWTC, DIFC or Downtown depending on attendee travel.
• Accommodation inventory (number of rooms for delegates and room blocks).
• Catering and dietary options, plus on-site team for F&B and logistics.
• Budget and package (daily delegate packages, room + meeting combos).
  (You can confirm exact floor plans, AV specs and current pricing with the hotel’s events or sales team; links above point to official event pages and Cvent layouts for floor plans.) (marriott.com)

If you want, I can:

• Narrow this to a shortlist of 3 based on your expected delegate count, preferred area (Downtown, DWTC, Palm, Festival City) and budget; or
• Pull current availability and sample daily delegate packages for one or two hotels and date ranges you have in mind.

Which would you like me to do next?
