Home Alone

Hello, my family and I booked the voyager of the seas for March 31st of 2025. I wanted to go ahead and book this trip as soon as it was released so we would get the lowest price. From my calculations this should be the week the kids are on spring break but now my wife seems to think it will be the following cruise on April 5th. I tried to get the refundable deposit but this ends up doubling the price of the cruise and isn't even an option online. So I currently have the 31st booked but am thinking about booking the April 5th as well and just canceling which ever cruise isn't sailing on the week we are on break. The deposit is only $400 and I'm sure that the price will increase more than that by the time of final payment but I'm wondering what yall's thoughts are. As I mentioned the nonrefundable price for either cruise is around $1675. After calling. since refundable deposit isn't available online, the price would be over $3000 making it not worth it. I won't find out which week is spring break until January 2024. If I do cancel Im guessing I lose the entire deposit. I wish they would let me use the deposit as cruise credit or even onboard credit but I know that's not how it works. Do you think it's worth booking both cruises to lock in the low rates and just take the hit on one of the deposits?
