Answer & explanation
Official answer
145,984
hotel rooms
How to estimate it
Fermi’s official “Napkin math”
There's no single number to grab here, so build it up. Guess how many hotels London has, maybe 1,500. Multiply by an average size, call it 100 rooms each.
- Hotels in London
- ~1,500
- Average rooms per hotel
- ~100
- 1,500 × 100
- ≈ 150,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Hotels in London (Sept 2024)
- 1,570
- Average rooms per hotel
- ≈ 93
- 1,570 × 93
- ≈ 145,984
