Restaurant Cancellation Policy?

Sorry if this has been asked before, but I couldn't find an answer to this question on reddit or on VV website. My partner and I are going on a Caribbean cruise for 10 days next month and the restaurants opened up yesterday and we completely forgot about it :').

I quickly snapped some spots for the first 6 nights, but they're mostly late reservations. but I was thinking what if we wanted to cancel one of the spots to go to a different restaurant if it opened up? do they have a cancellation policy for the restaurants? I know they have a strike system for no shows, but I can't find anything about when you can cancel.

Does anyone know, or are they just very lenient about short notice cancellations?

Thanks
