I have two long term clients with CC#'s in hand waiting to book tomorrow a back to back sailing tomorrow so I called RCI to get the scoop. I don't know about all their sailings but on this one you get a lower deposit amount, $200. per cabin OBC for each leg and some pretty attractive rates. All promo goodies are combinable with C&A benefits. There may be some other perks. I never read through all the promotion material I recieve, I'd never get anything else done.
hope this helps, Neil
