So we have cruise credit from last year that we have to book by April to use by Dec 22. We don't want to cruise this year. I don't want to deal with the COVID testing and restrictions with the small kiddos. I would rather just cruise next year in hopes it would be better. They still have the cruise with confidence until March 31. Could I book a cruise for Dec or Nov 2022. Then cancel it. Will it extend my cruise credit another year? Anyone did this or can verify this?
