I think I understand your question.... Is it... that you would purchase a Placeholder while on your Nov. 2025 cruise and want to use it to book an October, 2027 cruise? There's no telling when cruise itineraries will be release specifically, but, as you said, you have 2 years to book the 2027 cruise (from the day that you purchase it), so surely at SOME point in 2026, you will be able to use your Placeholder from the Nov., 2025 cruise to book your Oct., 2027 cruise. I hope that's what you were asking. Disregard if I've missed the point entirely
