Carnival has become very strict with the penalties for cancelling. I had a client back in the winter cancel exactly 12 hours after the penalties went into effect, bad situation, hubby left her and cleaned out bank accounts, left her penniless. She did not have insurance, of course insurance would not have covered that, unless it was the cruiseline insurance that gives 75% credit for a future booking. Anyhow the took her $500.00 deposit. We had to write a letter to the Research department of Carnival explaining the situation. They did give her a $290.00 credit for a future cruise, but it took them over 3 months to finally get it straight.
Again, this is another example of why clients need to purchase the insurnace. I hope all works out for them.
