@Joslyn6 this is a community forum so everyone here is a host or a guest apart from a few admins, so you are asking hosts here directly 🙂
However I am not sure what you mean when you say your guest is worried about the cancellation policy - what are they worried about in particular?
Have you read the policy so you can help advise your guests?
If you could clarify what it is that is of concern, happy to see if I can help, if it's not clear in the policy.
