I’ve found that we haven’t any tags for changing cubicles which we can find on any beach. Since I’m not a native English speaker I don’t know the best way to tag those instances: amenity=changing_room (very common and easy), amenity=changing_cubicle (because actually at the beach we haven’t rooms)? Should we use singular or plural (changing_room or changing_rooms, cubicle or cubicles)?
Or, may be, there is some better alternatives to tag those things?
And I think we should take into account American English speakers opinion.
