With social distancing requirements and elevators that were slow and inadequate in number to begin with, I wonder if cruise sips should be retrofitted with these:
It'll be a lot faster than long waits for slow rides. I guess another reason why I liked cruising on Ponant's Le Soleal - only 5 levels between bottom (restaurant) and top (aft bar) so the two elevators for pax wasn't necessary (only one staircase for pax towards the aft was a bit annoying though). .
The first (and actually, only) time I've seen one in action was at a valet parking garage in Reno. Surprised it got past OSHA but they've apparently been in use for a century and a quarter.
