A cruise deposit is a down payment required to hold your specific cabin and lock in your fare at the time of booking. In 2026, deposits typically range from $100 to $500 per person, depending on the length of the cruise and the stateroom category. This money is applied toward your final balance, which is usually due 90 to 120 days before sailing. If you book during a "Reduced Deposit" promotion, you might only pay $25 or $50. It is vital to understand the "Refundability" status: a Non-Refundable Deposit (NRD) is usually cheaper but means you lose the money if you cancel; a Refundable Deposit allows for a full return if you cancel before the "Final Payment" date. For 2026 "power travelers," booking with a refundable deposit provides a high-value safety net, allowing you to "price match" if the fare drops later or to change your mind entirely without financial penalty until the final countdown begins.
