Here are family-friendly hotel options in Mumbai organized by neighborhood (short notes on why each is good for families, plus nearby kid-friendly attractions and practical tips).

Colaba / Gateway of India (best for sightseeing, Elephanta ferry, historic walkable area)

• The Taj Mahal Palace — iconic, right opposite the Gateway of India (very convenient for the Elephanta ferry and Colaba sightseeing). (en.wikipedia.org)
  Recommended if you want luxury, easy access to the Gateway/harbour and family rooms/pool options. (thefamilyhotelguide.com)

Marine Drive / Nariman Point / Fort (central, seaside promenade, museums, planetarium)

• InterContinental Marine Drive — oceanfront, rooftop pool and short walks to Chowpatty, Kala Ghoda and museum areas. Good for easy evening strolls on the “Queen’s Necklace.” (intercontinental.com)
• Trident, Nariman Point / The Oberoi, Mumbai — luxury choices near Marine Drive and close to museums and the Fort/Kala Ghoda walking area. Good for family comfort and central location. (oberoihotels.com)

Juhu / Western Suburbs (best for beaches, pools, family resorts)

• JW Marriott Mumbai Juhu — beachfront, multiple pools including a kids’ pool and an on-site kids area; good for families who want beach time plus hotel amenities. (marriott.com)
• Novotel Mumbai Juhu Beach — family-friendly (kids’ club, children’s pool, kids’ menus), beachfront location and more mid-market pricing. (novoteljuhubeach.mumbainhotel.com)

North Mumbai / Gorai / Borivali (best if you plan on visiting Global Vipassana Pagoda, Gorai beaches or Sanjay Gandhi National Park)

• If your family plans the Global Vipassana Pagoda / Gorai area, consider hotels in Borivali/Malad and plan the ferry/drive to Gorai — the Pagoda is accessible from the Gorai/Marve ferry jetties. (globalpagoda.org)
• For Sanjay Gandhi National Park / Kanheri Caves outings, staying in north suburbs (Borivali/Thane) shortens travel time to the park’s trails and family-friendly nature spots. (SGNP contains Tulsi Lake and Kanheri Caves). (en.wikipedia.org)

Family attractions to plan around (quick notes)

• Gateway of India / Elephanta Caves (boat from Gateway) — ideal day trip if staying in Colaba/Marine Drive. (ihg.com.cn)
• KidZania (indoor role-play edutainment for kids) — located at R-City Mall, Ghatkopar (good for rainy-day family fun). (india.kidzania.com)
• Global Vipassana Pagoda / Gorai — reachable by ferry; nice open space for families and easy day-trip from central/west suburbs. (globalpagoda.org)
• Sanjay Gandhi National Park & Kanheri Caves — a nature/short-trek day trip suitable for older kids. (en.wikipedia.org)

Important/Current notes

• Taraporewala Aquarium (Marine Drive) has been closed / declared structurally unsafe and is under redevelopment plans — don’t count on it being open right now; check the latest local updates before planning a visit. (hindustantimes.com)
• EsselWorld / Water Kingdom (Gorai) has had closures in recent years; verify current status before planning a theme-park day. (en.wikipedia.org)

Quick tips for families

• Look for hotels that list “kids’ pool,” “kids’ club,” connecting rooms and babysitting services if you need them (many JW/Novotel/Taj/InterContinental properties list these amenities). (marriott.com)
• For Elephanta: book an early morning ferry from Gateway of India to avoid heat and crowds. (ihg.com.cn)
• Traffic in Mumbai can be heavy — for full-day family sightseeing consider staying in South Mumbai (Colaba/Marine Drive) to minimize travel time to major attractions, or pick Juhu if you want beach and relaxed hotel time. (en.wikipedia.org)

If you’d like, I can:

• Suggest a short 2–3 day family itinerary tied to one hotel (e.g., Colaba-based or Juhu-based), or
• Pull live availability/prices for specific dates at any of the hotels above.
