How to make an attribute for an erd entity that isn't always there

Question

I'm making an ERD that includes the relationship "entity tourist stays at entity residence". Entity residence could be a hotel or tourist camp. Each of those have their own specific attributes. How do I specify this in an ERD diagram?
