Hello. New to this board. I am looking at an NCL cruise 3 months from now. It's not a cruise I have to go on and we don't have to fly. I've been monitoring prices to see how much it would drop, and it seems to have dropped by ~$150 in the last few weeks. For the room type I am looking at, there were ~5-6 selectable rooms a few weeks ago, but now it's down to 2. Does this mean that this room type is about to sell out? Or do they hold some inventory for later. Also, since this is inside that penalty free cancellation window, I assume once I book it's not cancellable? No 24 hour free cancellation like airline tickets? Thanks for any advice.
