• (Other luxury brands with seasonal deals) — JW Marriott (Sahar/Juhu), The Westin, Four Seasons, etc., regularly run limited-time or member offers; check each hotel’s “Offers” page or the brand loyalty portal. (marriott.com)

What “seasonal discounts” look like

• Third‑night free / stay‑longer offers, advance‑purchase discounts (10–20%), F&B/spa credits or percentage discounts during festival periods, member‑only rates, and package bundles (breakfast + transfers + experiences). (Examples above.) (fourseasons.com)

Best ways to find & lock the seasonal discount

• Book direct on the hotel brand’s “Offers” page (hotels publish official seasonal/limited offers). Use the hotel page when you see specific validity dates. (fourseasons.com)
• Join the hotel loyalty program (Marriott Bonvoy, Accor ALL, Taj InnerCircle/NeuPass, ITC club) — members often get member rates, bonus discounts or early access to sales. (vistana.com)
• Compare direct rates vs OTAs (Booking/Expedia) and check “advance purchase” non‑refundable vs flexible rates — advance purchase can give bigger discounts but with stricter change/cancel rules. (See brand advance‑purchase offers as examples.) (fourseasons.com)
• Sign up for hotel newsletters or follow hotels on social for flash sales & festival packages. Many seasonal offers are time‑limited and published only on the hotel site or via email.

Notes & caveats

• Offers change frequently (validity windows, blackout dates and inclusions differ). the examples above were verified on official hotel/brand pages and press pages as of Sep 14, 2025 — always confirm dates and terms on the hotel’s current “Offers” page before booking. (fourseasons.com)

If you want, I can:

• Check live rates and seasonal offers for a specific hotel and exact travel dates (I can search availability and current discounted rates for, e.g., Sep–Dec 2025); or
• Compare 3–5 hotels for a particular neighborhood (Colaba, Worli, BKC, Juhu) and show current promotions side‑by‑side.
