I was on the Fantasys and I think it was about 18 months for bookings. I don't remember off hand for announcement. With that said, I asked about the obb. At the moment,
DCL has not made any plans for obb and placeholders. It could go either way and it could be some things but not others honored. Now on Maidens typically there are restrictions and changes vs say a normal 4 day cruise. Deposits are higher and non transferrable and non refundable. Not the 20% down as it is now. Iirc your pif is 120 out and not 90 days. If DCL changes the date, they'll offer you some cabin etc, and I think that's the only way you'll get a refund, is if it's on DCL for the change. Otherwise your committed.
