Most of these things run about $100/day. We'll check NO, I'm not sure which lines run out of there, but my sneaky suspicion is that the have older ships...like Galveston. Running out of TX or LA will take away one port of call.
Well! An older ship, unless it is a really, really ELEGANT older ship, will never do!
OTOH, N'Awlins is a fun place to start and end a party!
What ports are under consideration?
