I need to cancel for weather. What happens?
Nothing is held against you. The decision to sail is yours alone, the guest's deposit is refunded or the trip is moved, and it does not count as a cancellation on your record.
You are the only person qualified to make that call and we will never lean on you to run a trip you are not comfortable with. Guests are told plainly in their own help pages that a weather call is the captain doing their job.
Offer an alternative date if you have one. A great many guests would rather move than be refunded, particularly if they are here for another few days.
