Here are major hotel loyalty programs that routinely provide member-only discounts/benefits at hotels in Mumbai, with example Mumbai properties and the type of discount to expect:

• Marriott Bonvoy — member rates and direct-book discounts (examples: JW Marriott Mumbai Juhu, JW Marriott Mumbai Sahar, The Ritz-Carlton Mumbai, Courtyard/Fairfield properties). Marriott has run a “Book Direct / member rate” discount (e.g., 5% member savings on Mumbai hotels). (marriott.com)

• Taj InnerCircle (IHCL / Tata Neu) — tiered member savings on Best Available Rates (e.g., 10% for Silver, 15% for Gold, up to 25% for Platinum) plus dining/other member perks at Taj properties in Mumbai (Taj Mahal Palace, Taj Lands End, Taj Santacruz, etc.). (tajhotels.com)

• Oberoi One — member-only savings (members typically receive at least a 10% saving on stays) at The Oberoi, Mumbai and other Oberoi properties. (oberoihotels.com)

• Hilton Honors — member rates, bonus-points promotions and property-level member offers at Hilton hotels in/near Mumbai (for example Hilton Garden Inn Mumbai International Airport has Honors member offers such as points promotions and advance-purchase/member discounts). (hilton.com)

• World of Hyatt — member promotions (Hyatt runs India/South‑Asia Member Day and other member-only sales) for Hyatt properties in India when participating (check participating Hyatt/Mumbai hotels for current Member Day participation). (hospitalitybizindia.com)

• IHG One Rewards — member rates, points on stays and India-specific member dining discounts (IHG has offered food & beverage discounts for IHG One members in India). Example Mumbai IHG hotels include InterContinental and Crowne Plaza properties. (ihg.com)

• Accor ALL (Accor Live Limitless) / Accor Plus — member rates, bonus points and occasional member-only discounts at Accor brands in Mumbai (Fairmont, Novotel, ibis, Pullman where present). Accor advertises member rates and member savings on participating properties. (fairmont.com)

Quick notes and tips

• Benefits vary by brand, hotel and your membership tier: typical perks include an exclusive “member rate” (usually a percent off the public rate), bonus points, free Wi‑Fi, dining discounts, and periodic member promotions. Always log in to the loyalty site before searching to see member rates. (marriott.com)
• For the best guaranteed discounts: join the brand’s loyalty program (most are free), then book directly on the brand website/app or call the hotel and request the member rate. Some programs also require booking specific member‑only promotional rates to get the advertised savings. (marriott.com)
• Dining/spa discounts: several programs (IHG, Taj, Accor, Marriott via local offers, etc.) also include F&B or spa discounts for members at participating Mumbai hotels — check the hotel’s offers or member T&Cs before you go. (ihg.com)

If you’d like, I can:

• Check current member-only rates for specific Mumbai hotels and your travel dates, or
• Compare likely member savings for 2–3 hotels you’re considering (I’ll look up live offers and dates).
