🧠 Clarification First:

• ​ Only considering hotels, excluding Airbnb/lodges
• ​ City in focus: Bangalore

⸻

🗺️ Step 1: Estimate Area

• ​ Total area of Bangalore ≈ 600 km²
• ​ After removing lakes, forests, and parks, assume 50% usable land → 300 km²

⸻

🧩 Step 2: Zoning by Density

Divide usable land into 3 zones by density (normal distribution):

🔹 High density (25%) → 75 km²

🔹 Medium density (50%) → 150 km²

🔹 Low density (25%) → 75 km²

⸻

🏨 Step 3: Hotels per Zone

🔸 High Density → 5 hotels/km² → 375 hotels

🔸 Medium Density → 2.5 hotels/km² → 375 hotels

🔸 Low Density → 0.5 hotels/km² → ~35 hotels

➡️ Total Estimated Hotels: ~800

⸻

📊 Gut Check Using Demand

• ​ Population ≈ 1.5 Crores
• ​ Assume 1 in 1000 is a tourist → 15,000 tourists
• ​ Average hotel has 20 rooms
• ​ To host 15K people → Need ~750 hotels (15,000 / 20)

✔️ Matches well with the estimated 800 hotels

⸻

This structured guesstimate blends logical assumptions, population metrics, and land analysis to arrive at a solid ballpark figure.
