We strongly recommend purchasing travel insurance due to the vendor's very strict cancellation policies. This is to confirm that you are aware of the cancellation penalties as described above on this page and that travel insurance is available for purchase to protect against cancellation penalties due to unforeseen MEDICAL reasons.
Carnival's Value Protection Plan is $49 per person for interior and ocean view cabins and $79 per person for balcony cabins.
Third party insurance can be added as well contact me directly and we can discuss those options.
