Oops! I didn't catch that your D0 cruise was later in this year. Maybe, just maybe, you could talk to an in-the-know-officer and get some information. After 3+ pages on CC this is a current hot topic. Actually, what we all would want is for you to walk up to a D0 cabin and ask,"Whatcha gettin'!".
Anyway, somebody will put this to rest sooner than later.
