Rule 5 is quite simple to apply, regardless of where you are. However, prior permission to land at a private location such as a hotel should be obtained from the owner prior to arrival. Even then, some people will push the limits by making their approach as close as possible to any obstructions , such as passing low over the roof of a hotel in the middle of nowhere. (I witnessed such a happening with a 206 arriving on Lundy island some years ago. The machine passed so low over the hotel roof that it caused some roofing tiles to flutter.)
In the thread "Helicopter ace lands in court", nobody has said whether the landing at the hotel was with prior permission of the landowner, irrespective of how many persons were present.
