Answer & explanation
Official answer
411
years
How to estimate it
Fermi’s official “Napkin math”
Vegas is packed with giant hotels. Picture 30-odd mega resorts at roughly 3,000 rooms each, plus all the smaller places. Call it 150,000 rooms. One night each, split over 365 days a year.
- Vegas hotel rooms
- ~150,000
- One night each
- ÷ 365/yr
- 150,000 ÷ 365
- ≈ 410 yrs
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Hotel rooms in Las Vegas
- ≈ 150,000
- One night per room
- 150,000 nights
- ÷ 365
- ≈ 411 years
