I have never used Cruise First, but have used Cruise Next a lot. The $250 per CN comes off the total, which includes base fare, taxes, port fees, etc. Is there such a thing as a seven day NCL cruise that has out the door pricing of less than $500? According to CruisePlum, the cheapest total price booking currently available on NCL is a 12 day Orlando - Rome inside cabin for one passenger at $1210.
