Here are luxury hotels in Singapore that commonly run seasonal discounts, with current examples you can book or watch for. I’ve included one active/representative offer for each (sources linked):

• Raffles Singapore — Book‑Early / Advance purchase deals (example: “Book Early with Raffles”: 15% off Best Available Rate with advance‑booking requirements). (rafflessingapore.com)

• Shangri‑La Singapore — Large seasonal promotions (example: “SG60” promotion: 60% off the third night for qualifying stays and other seasonal bundles). (shangri-la.com)

• Marina Bay Sands — Suite/long‑stay packages and seasonal resort credits (example: “An Extended Indulgence” for Paiza/Paiza Collection suites with resort dollars and multi‑night perks). (marinabaysands.com)

• Capella Singapore (Sentosa) — Resort packages and periodic promos (examples: “Celebrate Easter” with ~15% off BAR + resort credit; “Third night on us”/villa getaway promotions). (capellahotels.com)

• The Fullerton (Hotel & Bay) — Advance purchase, “stay more save more” and member/partner promotions (examples: advance‑purchase discounts up to ~20–25% and periodic member/card partnerships). (fullertonhotels.com)

Quick notes and booking tips

• Many luxury hotels run: advance‑purchase discounts, “stay X nights get Y free” deals, bank/credit‑card partner promotions, holiday/festival packages, and member‑only rates. These patterns repeat seasonally — check each hotel’s “Offers” page.
• Best practices: compare the hotel’s “offers” page vs. the Best Available Rate, join the hotel’s mailing list/loyalty program (member rates often beat third‑party sites), and check bank/credit‑card partner pages for extra discounts or credits.
• If you have flexible dates, use multi‑night windows (weekdays often cheaper than weekends) and search vendor aggregators (e.g., the hotel site, Luxury Escapes, or the hotel’s booking app) to catch flash promotions.

If you’d like, I can:

• Compare current rates and available seasonal packages for specific dates (I can check these hotels side‑by‑side), or
• Watch for specific promo types (e.g., 3rd‑night‑free, bank card offers) and list the best active deals today.
