I had a call earlier on from TA with 3 options.
1 Take a different cruise with Cunard
2 Take the offer on the table (4 days in dock in Barcelona and $100 OBC)
3 Full refund
I don't understand why they don't offer more OBC. Some people will take into account the hassle value of cancelling flights and hotels, dealing with insurance etc and the financial loss (excess etc). As it stands I think they will struggle to fill the ship. Its not very attractive as it stands, at least more OBC would make it more attractive.
I have never sailed with Cunard. Also, I have never had an experience like this with other cruise companies so hard to compare how Cunard have handled it compared to others. However, with their original derisory offer and the way it has been handled it has put me off Cunard and I doubt if I would consider them in future.
