Carnival just cancelled two cruises we have booked 7/10/2021 and 10/09/2021 because my husband uses oxygen. We are long time cruisers with Carnival and they have been aware for the past 3 years of his disability. We are also both fully vaccinated. But, they are now allowing un vaccinated persons to cruise and are taking their booking. This is totally wrong. They have announced no cruises for anyone with disabilities right thru the end of 2021.
