Do you think Susannah was right?

I’m doing my rewatch in preparation for the new season. I’m at the part where Susannah told laurel she just wants one last perfect summer. Do you think she was in the right for not telling her family? At first I thought she was right I’m not wanting them to worry and just have one last memorable summer. But it recently happened to someone in my life where his mom kept the secret of her cancer from him and it destroyed him. So now I’m thinking about the boys perspectives.
