My daughter's bf is a pit boss who travels not on certain ships, but only Ultra, Elite, etc. cruises. So, for example, he'll get finished with an Ultra cruise coming back to Baltimore then fly down to Tampa to catch an Elite cruise that departs next day. He said there are factors used to determine the offer, and sometimes the factors fall within overlapping cycles and stopped there, saying it's hard to explain. Anyway, what I think it means is one of your factors (who knows... "first" Carnival cruise and they know your history with NCL?) is putting you in the "better offers" category right now. Best I'm getting right now is free balcony, 7-day, free drinks while gambling, $250 in FunPlay chips. I have gotten better offers in the past, and I've gotten "not as good" offers. We're booked on a free 10-day in early September out of Rome with $500 FunPlay and I'm holding out for something at least in-between my current offers and that one.
