I sincerely hopes it works for you. After our Seashore transatlantic was cancelled in Oct., we were offered $200 ($100 each) compensation if we booked 7+ days cruise. We are on the 14 day cruise we booked with the cancelled cruise credit. The compensation did not show up on our shipboard acct. I have the compensation email, the cruise papers, and an email from existingreservations.com verifying that we HAVE $200 ($100 each which is how it is listed by our individual billing sheets) but, so far, we've only been granted $100. We had another $50+$50 for VC 5%+15% (also clearly stated on the booking) which had not been given to us until brought to their attention.
The reason given for only $100 was wording (per cabin) on the FCC/Compensation email( which also clearly stated $200). Supposedly, they are waiting for corporate to affirm what my paperwork and follow-up email states.
It may turn out as promised. I will let you know if that is the case.
Just be aware, and perhaps, be armed with email addresses you may want to use, should you be left powerless by Guest Services. For me, I am working hard at practicing ACCEPTANCE.
