Quick tips

• Memberships matter: you’ll often get the best published perks by booking directly and using the hotel’s loyalty program (e.g., Four Seasons reservations, Taj NeuPass, Leela DISCOVERY / Oberoi One / Marriott Bonvoy / Club ITC). (fourseasons.com)
• Dates and inventory change fast — special rates, blackout dates and booking windows vary by offer; always confirm the exact validity and cancellation terms on the hotel’s offer page before booking. (All offers above were checked on Sep 14, 2025.) (fourseasons.com)

If you want, I can:

• Compare total price for two or three hotels on a specific date range, or
• Check availability and the cheapest eligible promotion for your travel dates and party size.

(If you want that comparison, tell me exact travel dates and number of guests and I’ll pull live rates.)
