I just had to cancel my 5/21 sailing on the Vista. I tested positive within 10 days of sailing. I called to cancel, and the FCC had to be applied to a cruise sailing within 12 months. I had 2 sailings booked for later this year, so I applied the FCC to those. My port fees/taxes, I was able to apply to a cruise in 10/2023. I was not refunded my Carnival insurance fee. I did email in my Positive test result.
If I had thought about it, I would have called back and tried to get another agent, but I did not feel up to it.
I had spoken with someone in Fun Shops, regarding cancelling my pre booked items, but she transferred me before I got confirmation of the cancellation. I am now checking my credit card account, looking for the refund.
