We are booked September 25 from Long Beach 4 cabins 8 adults 5 children. This change does not give us a long enough pre warning to get our money back on the cruise based and carnival's rules which since it does not give ample notice to cancel is an unfair rule. To get all of us tested will be $2700 extra out of pocket expense, discomfort for the children who are too young to be vaccinated since they will have to be tested twice in 3 day period of time, not to mention since we arrive 3 days early and do not have a vehicle a challenge to get tested. I understand carnival taking its cautious approach but it should allow us to cancel for a full refund since it was Carnival who made the change in the rules without long enough warning to get a full refund. Again I know this is a difficult time for the cruise industry but I should not be penalized for their failure to give ample notification to cancel with a full refund
