Exactly this. Cunard did not inform anyone that an option to check-in and receive room, board and transportation would be made available. Only those already onboard, those who didn't receive the email cancellation, and those who ignored the email or were already at the pier received those benefits. The rest of us were abandoned with a “ sorry for the inconvenience” email. This is, intentional or not, definitely a double standard.
One can attempt a defense of Cunard with remarks such as “be prepared when traveling,” or “these things happen,” or “Cunard's T&C applies,” etc. But those remarks ignore the fact that not all were treated the same and that many of us incurred thousands of dollars to return home while others did not.
