Maybe a better idea would be to convince the hotel to fix their buggy, underengineered elevators. I've never understood why it is even POSSIBLE to overload an elevator with people; to my mind, an elevator that can be overloaded in that way is underdesigned.

Overloading it with heavy objects (say, dealers transporting books) is another matter. One might reasonably expect that a hotel would not bother to have its elevators designed for that load, as it rarely happens.
