The official answer, with Fermi’s reasoning step by step.
Answer & explanation
Official answer
2,350
crew members
How to estimate it
Fermi’s official “Napkin math”
Icon is one of the biggest cruise ships ever built, so start with the guests. Call it 6,000. How many crew to look after them? Someone is always cooking, cleaning or serving, so maybe 1 for every 3 guests.
- Guests aboard
- ~6,000
- One crew member per
- ÷ 3 guests
- 6,000 ÷ 3
- ≈ 2,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Guests at double occupancy
- 5,610
- Guests per crew member
- ÷ 2.39
- 5,610 ÷ 2.39
- ≈ 2,350
