9. Ritz / Millenia, Pan Pacific, Fairmont/Swissôtel and JW Marriott (summary recognition)

• Note: Singapore hotels regularly rank highly in MICE/hotel lists (Cvent, TTG MICE) — planners often rely on Cvent rankings and the Singapore Tourism Board for up-to-date MICE venue facts and RFP sourcing. If you want a “top meeting hotels” shortlist, Cvent lists and the VisitSingapore MICE pages are good reference points. (cvent.com)

Quick planning tips

• Book early: Singapore is a top MICE city year‑round (high demand) — major venues book many months (often 9–18+) in advance. (cvent.com)
• Ask for an event fact sheet and hybrid/AV package: large venues (Marina Bay Sands, JW, Ritz, Fairmont) offer dedicated hybrid studios and in‑house AV partners. (marinabaysands.com)
• Check transport & hotel room blocks: prioritize hotels with direct MRT access or short transfers for delegates (e.g., Raffles City / City Hall area, Marina Bay Sands, JW South Beach). (cvent.com)
• Sustainability & certifications: if important, request the venue’s sustainability / SACEOS or EIC certification info (many large venues publish this). (visitsingapore.com)

If you’d like, I can:

• Narrow this list to a shortlist by required capacity (e.g., 50 / 300 / 1,500 delegates);
• Produce a short RFP/email template you can send to 3–5 shortlisted hotels;
• Compare estimated costs (venue hire + AV + F&B) for one of the hotels above (you’ll need to give target delegate numbers and preferred dates).
