I built up on my nerve and successfully used the old-fashioned elevator at the hotel I’m at in Frankfurt. It’s a continuous, and continuously-moving, loop of open cubicles, large enough for two skinny people, or one American. No waiting, no doors. You step in as an empty compartment approaches and hop out as it moves past your floor.
The clerk assures me that there have been no injuries, although it seems easy to hurt yourself: mis-time your exit and you will be part way between the elevator and the floor as the elevator moves on. I’m surprised the lobby isn’t littered with severed arms and torsos split cleanly in two.
On the other hand, I only got in once the clerk assured me that if I panicked and was unable to force myself to hop out, it doesn’t turn the compartments upside down at the top of the loop.
Damn thrilled-crazed Europeans!
