$40. per person. I just finished calling all my clients affected by the first batch today. Costa hasn't yet had their system updated to reflect the add'l cost and take the payment but they're working on it. Also many of the Carnival sailings have not yet recieved the formal notification but will. The first batch I got was all Princess and HAL. From what I hear, there are more notifications to come.
On a good note, I only had a couple of clients that were really verbally upset and none of them cancelled. Most were very understanding, more understanding than I'd have been to recieve that call.
Enjoy your rose... I mean your cruise!
