For our upcoming cruise, I called NCL directly and said the price has gone down and I would like a price adjustment. Most of the time the agents were knowledgeable how to handle it, but once or twice the agent said they would put in a request. I then said never mind, hung up and called again.
Now what I find interesting is that since we booked this cruise, the DSC did go up, but our original DSC amount was kept with all of the price adjustments.
Also, now that we are in the final payment stage, I did call for my one-time-only FCC for a price drop and were just notified we got an approval of $640 to be used within one year from our next sailing.
So in total, we saved over $4,000 (I am including the FCC since we do have a cruise booked for this August where we will use the $640) by constantly checking the updated prices.
Call and let us know your outcome!
