Out of curiosity I counted the number of available cabins on the Fantasy sailing on December 21st. I know that this is not scientific, but by my count there are approximately 550+ available cabins for booking. I looked online and there are 1250 cabins on the ship. Assuming they book some of those cabins through last minute bookings, would they sail that ship at nearly half capacity (I mean there are almost 20 concierge rooms available, which is where they make pretty substantial bucks). Anyone know what they usually do in these types of situations?
