How Do I Cancel My Margaritaville Cruise? Description: To cancel your Margaritaville cruise, contact Margaritaville at Sea Customer Care rather than trying to cancel through the online Guest Portal. The current policy states that cancellation fees vary according to the number of days before departure and cruise duration. If eligible, refunds can be subject to applicable cancellation charges and booking terms. https://www.cruisesfares.com/blogs/how-to-cancel-margaritaville-cruise
