Yes — many Singapore hotels run "early bird" / advance-purchase rates. Below are examples (checked on Sep 14, 2025) with the typical terms so you know what to expect:

• Shangri‑La Singapore — "Book Early and Save" / "Book Early and Save with Flexibility": tiered discounts (e.g., ~15% if booked 14 days ahead, ~20% if booked 21 days ahead). Often requires full prepayment for the advance rate (terms vary by offer). (shangri-la.com)

• Four Seasons Hotel Singapore — Advance Purchase: up to ~20% off when you book at least 7 days in advance; usually non‑refundable / prepaid. (fourseasons.com)

• Fairmont Singapore — "7 Day Advance Saver" / "Advance Saver with Breakfast": typically ~10% off if booked 7+ days ahead; breakfast options available on some advance packages; usually non‑refundable. (fairmont-singapore.com)

• Pullman Singapore Orchard — "Advance Saver": advertised savings up to ~30% for early bookings (subject to availability and blackout dates). (pullmansingaporeorchard.com)

• PARKROYAL / Pan Pacific properties (Parkroyal on Beach Road, Pan Pacific / PARKROYAL serviced suites) — Advance Purchase packages with stepped savings (e.g., book 21/30/60/90 days ahead for increasing discounts, sometimes up to ~25–35%). (panpacific.com)

• M Hotel Singapore (Millennium) — "Earlybird Special": advertised up to ~27% off when booking a week or more in advance (member rates/extra perks if you join the programme). (millenniumhotels.com)

• Mercure Singapore on Stevens — "Advance Purchase Special": example offer showing small advance booking discount (e.g., ~5%) plus included benefits on some packages. (mercure-singapore-stevens.com)

How these offers generally work (important points)

• Names: hotels call them "Advance Purchase", "Advance Saver", "Early Bird", or "Book Early and Save." Search the hotel website under "Offers" or "Promotions." (shangri-la.com)
• Prepayment & cancellation: most advance/early‑bird rates require full prepayment at booking and are non‑refundable or strictly no‑change. Check the rate rules before booking. (fourseasons.com)
• Discounts vary by lead time and property (examples above range ~5%–30%+). Blackout dates and minimum lead times apply. (pullmansingaporeorchard.com)
• OTAs & credit‑card promos: online travel agencies (Agoda, Booking, Expedia) often list prepaid "advance" rates and run card‑holder promotions; compare OTA prepaid offers vs. booking direct (direct booking can carry member benefits). Look for "prepaid" or "advance purchase" tags. (americanexpress.com)

Quick advice

• If you need flexibility, avoid prepaid advance rates (they're cheaper but usually non‑refundable). (fourseasons.com)
• Compare the hotel's "Offers" page and OTAs (filter for "Advance/Prepaid") — sometimes OTAs have special promo codes or card discounts that beat the hotel's direct advance rate. (cardpromotions.hsbc.com.sg)
