I've search and can't seem to find the answer to this. I have a cruise planned this December. If I call Costco on October 4th to book one of the 2020 cruises, then what happens if I want to take advantage of the discount if I book onboard in December? Or am I just out of luck as far as the onboard booking discount?
Also, what happens of I later want to change that booking to another cruising?
