I have used points in the past and redeemed them a few weeks or a month before the cruise. We redeemed for OBC to be used once on the ship. But I have a different situation now. We booked a European cruise for August 2025 and only have a small amount of OBC. We've have a lot of points to redeem so we could get more OBC so that we could book some excursions before they are sold out. My question is if we trade in the points now to book excursions or upgrade drink pkg, what will happen if we had to cancel the cruise (or Celebrity cancels). I think once the points are redeemed they are not refundable. Is that correct? If so what have people done?
