Our cruise price [after final payment] dropped $2000.00 in March and my TA put in a request for FCC and a week later we got an email approving it. 2 weeks ago the price dropped another $2000.00; I emailed my TA; she sent in another request for FCC. NCL replied - they only give one courtesy FCC after final payment. So sorry.
If I had known, I would have requested closer to the sail date. Live and learn.
