Correct, the question being asked was what happens if the GUEST cancels before PIF. In that case, for concierge the deposit is nonrefundable.
Again, I was answering the specific question the OP asked, which was what if they voluntarily paid in full but before their PIF date. I was clarifying that if they one one of the cruises with an "extended" PIF date, and were only before that date, but not before the original PIF date, they would be subject to ordinary cancellation penalties. The delayed PIF was given as an option: guests could choose NOT to pay in full prior to the revised PIF date (in which case their deposit would go into forfeiture if they cancel, but the "benefit" is that they would not be risking more than the deposit because that is all they paid to
DCL). But once a guest chose to pay in full before the revised PIF date, they were treated as having "opted out" of the delayed PIF, and were subject to the original cancellation schedule.
I agree that is pretty stupid, but that's what DCL CMs were saying. I also think the way they treated my cruise was stupid: I had a May cruise that per the website could be moved to a new date for 100% FCC up until the day before the cruise. I moved mine under that offer, but was told moving it made the whole reservation non-refundable in its entirety, even though I was only in the phase where I'd lose the deposit. I thought that was nuts but agreed to it.
In both cases, DCL is definitely making clear that they are offering an accommodation not to help guests but to lock in their money. Left a sour taste in my mouth but that is what it is.
