Unless it is exposed electrical wiring or something without insulation, it shouldn’t be a functional safety issue. All the cable I work with has already been insulated when you are running it, the hiding part is just for appearances/so people don’t trip on anything (which presumably they would not do on the ceiling). Now I have no idea if they are talking about electrical cable, ethernet, fiber, etc. There are a lot of cables that typically run through a hotel.

If it is electrical, maybe an issue. If it’s an exposed fiber line the biggest risk is just the guest breaking it.
