I do see what I think might be a minor gotcha on this. Booking the lowest category price within a meta category means a non-refundable deposit these days, or so I've been told by my PVP. The promo says it's for new bookings only. So, in my case if I canceled and rebooked an upcoming, getting the better cabin for the lower cabin price, wouldn't that mean a non-refundable deposit? For me, that makes it a gamble, betting that nothing will prevent me from actually going on the cruise. Hmmm.
