Elevators/Escalators from Kone
KONE will design, supply and install altogether 60 custom designed elevators and 12 escalators tailored for passenger and service use.
Meaning 15 elevators and 6 escalators per ship.
I can't believe my math is that bad. I meant to write 30 elevators per ship, not 15. So I take back all that I wrote earlier about 15 elevators not being enough, as there will be more than 15 of them on each ship.
