If it is a separate lift something as simple as RULES NOTICES on the way up the drag lift or chairlift depending on what you have there...
With a warning that you will be asked to leave the park should you not follow health and safety rules...
It doesn't matter where in the world you go, they have paid the same as everyone else and it is there RIGHT to annoy others in the park, but the rules and notification that liability is theres should they cause an accident, may help a lot more than you think...
