Short answer: true “all‑inclusive” resorts (meals + drinks + activities bundled) are uncommon inside Mumbai city — most family‑friendly hotels there offer family packages or meal‑inclusive rates, while nearby getaways (Alibaug, Lonavala, Khopoli/Imagica) offer fuller all‑meal / activity packages. Below are well‑rated options (in Mumbai and within ~2–3 hours’ drive) that advertise family packages or full‑dining packages.

Quick notes before the list

• If you mean fully all‑inclusive (all meals, drinks and activities), check the package details carefully — many properties label offers “stay + meals” or “family getaway” rather than classic Caribbean‑style unlimited all‑inclusive. (travelmyth.com)

Top options to consider

1. Radisson Blu Resort & Spa, Alibaug — full dining / stay & dine packages (breakfast + lunch + dinner options), kids policy noted (young children often complimentary); resort has kids pool, activities and family amenities. Good for a beach weekend ~2–3 hrs from Mumbai. (radissonhotels.com)

2. Taj Alibaug Resort & Spa — advertises “Family Getaways” and multiple package options (meal‑inclusive rates and family offers); luxury beach resort with family villas and kids amenities. (tajhotels.com)

3. Tropicana Resort & Spa, Alibaug — family‑friendly resort with on‑site dining and activities; often packages for families and group bookings (good beachfront value option). (tropicanaalibaug.com)

4. Della Resorts, Lonavala — strong family packages that bundle breakfast and dinner and offer packaged adventure‑park passes / family offers (Della Adventure Park + shows); good if you want activities for kids. ~2–3 hrs from Mumbai. (dellaresorts.com)

5. Novotel Imagica (Khopoli / Imagicaa area) — packaged offers that combine stay + breakfast + theme/water‑park access + dinner (family packages available). Good if you want a resort + theme‑park combo close to Mumbai. (imagicaaworld.com)

6. Novotel Mumbai Juhu (and other Accor/Novotel properties in Mumbai) — strong family programs (kids often stay & eat breakfast free; family room offers / discounted second room). These city hotels provide easy access and family perks though not always full all‑inclusive. (novotel.accor.com)

7. Lemon Tree / Aurika / other Mumbai hotels — many list “family rooms” and meal‑inclusive rates or family offers (useful for shorter stays in the city; check each hotel’s current family package). (lemontreehotelsmumbai.com)

Practical tips

• Ask each property specifically: what “all‑inclusive” covers (which meals, alcohol, kids’ meals, included activities, age limits, taxes/fees, blackout dates). Package names can be misleading. (radissonhotels.com)
• For true meal + activity bundles, Alibaug and Lonavala resorts are likeliest; for quick family perks (kids stay free, breakfast included), city hotels (Novotel, Lemon Tree, Aurika) are easiest. (radissonhotels.com)
• Check dates and availability (weekends and holidays sell out fast) and compare package totals (sometimes booking a B&B + paying à la carte can be cheaper than a labelled “all‑inclusive” package).

If you’d like, I can:

• Pull current package prices/availability for any one or two of the properties above for specific dates; or
• Narrow suggestions by travel time (within Mumbai city vs. 1–3 hour drives) or by budget (economy / mid / luxury).
