American Cruise Lines' 24-hour cancellation policy allows you to reserve your cruise knowing that if you change your mind within 24 hours you will receive a 100% refund. Cancellation requests must be received within 24 hours of initial payment. After 24 hours cancellation charges apply.

In 2026, the ability to cancel a cruise within 24 hours of booking for a full refund depends entirely on the cruise line's specific policy, as there is no federal "24-hour cooling-off" law for cruises like there is for airline tickets. Major lines like Royal Caribbean, Carnival, and Norwegian often offer a "24-hour hold" or a grace period where you can cancel without penalty if you booked directly and haven't made the final payment. However, once a deposit is paid on a "Non-Refundable Deposit" fare (which is the most common discounted fare), that deposit is usually lost immediately upon cancellation, even within minutes of booking. Some lines, like Disney Cruise Line, are slightly more lenient, but even they have strict windows. To protect yourself, many travelers utilize the "Book Now, Pay Later" features or purchase "Cancel For Any Reason" (CFAR) travel insurance. If you realized you made a mistake within 24 hours, your best bet is to call the cruise line immediately; while not legally required to refund you, many will allow a one-time "courtesy correction" or move your deposit to a different sailing if you act quickly.
