My attitude to those hotels who expect that helicopters will pay for a landing is to ask how much they charge cars to park in the car park and use their hotel facilities. If they put the argument forward that they have had to go to some costs to make the helipad, ask them how much it cost them to build the car park. I have refused on many occasions to pay a landing fee on the basis that I am using the hotels facilities. Oh yes I will pay if the landing site at the hotel is all that I will use as my convenience to visiting some place nearby.
If you use the hotels' facilities you should NOT pay landing fees - point this out firmly to the manager.
