Most Fever tickets are final and cannot be refunded.
Some experiences, however, do allow reschedules up to 48 hours in advance: you can check this in the experience’s FAQs linked in the experience description.
If you would like to reschedule your ticket and the experience allows it, please contact us and include the ticket ID associated to your purchase (What is the ticket ID?). One of our representatives will respond to your request as soon as possible with the next steps to follow.
