How does Viking handle a change of departure date relative to refunds?

[OnTheJourney]

I'm considering moving a cruise for March to the following year. The price is lower in 2020 (not the only reason for the move however) so how would they work that? I already paid in full...so is all of it returned (minus the $100 pp penalty for any sort of cancellation / change)? Or are there additional penalties such as perhaps forfeiture of the initial ($1k) deposit. If that would be the case, I wouldn't consider changing my existing reservation. But given the significantly lower 2020 price, even with the $100pp penalty I still come out ahead. Any thoughts from anyone who has perhaps done changes or cancelled?

 

Just checked the website....it appears under "terms and conditions" that indeed all money paid to them is refunded - so assume this includes the deposit.
