Onboard credit is money applied directly to your shipboard account, but the fine print — refundable versus non-refundable, use-it-or-lose-it deadlines, and how much a travel agent can stack on top of the cruise line's own offer — is where most cruisers leave value on the table. Getting the most out of it means understanding exactly what kind you have and spending it deliberately before the cruise ends.
Refundable vs. non-refundable OBC
This distinction determines what happens to unspent credit, and most cruisers never check which type they have. Non-refundable OBC — typically a gift from the cruise line — is use-it-or-lose-it; anything left unspent at the end of the cruise simply disappears. Refundable OBC, usually offered by a travel agency, gets returned to you via your original payment method or a check within 30 days if you don't spend it all.
| Type | Source | Unused balance |
|---|---|---|
| Non-refundable OBC | Cruise line promotions, loyalty perks | Forfeited — use it or lose it |
| Refundable OBC | Travel agency booking bonuses | Refunded within 30 days of unused portion |
Booking through a travel agent who stacks their own onboard credit on top of the cruise line's promotion is the single biggest lever for maximizing OBC — agency credit can top what the cruise line offers on the same cabin.

The biggest 2026 strategy is stacking multiple offers on a single booking: booking during Wave Season through a travel agent who adds their own OBC on top of the cruise line's existing promotion can add $500-800 in combined value to one stateroom. During Wave Season 2026, cruise lines themselves offered $100-600 in OBC per stateroom on top of reduced deposits, free drink packages, and complimentary wifi — all stackable with an agent's additional credit.
| Source | Typical value |
|---|---|
| Cruise line Wave Season promotion | $100-600 per stateroom |
| Travel agent booking bonus | $50-200 on top of the line's offer |
| Triple-stacked (agent + line + additional promo) | $500-800 combined |
Tracking your OBC balance throughout the cruise and planning a specialty dinner, spa treatment, or shore excursion around what's left avoids scrambling to spend it down on the final evening. [Replace this box with your actual onboard spa/dining affiliate link once approved.]

Most cruise lines place few restrictions on how OBC is used — if a purchase can be billed to your onboard account, credit usually covers it. Common uses include shore excursions, specialty dining, spa treatments, drinks, retail purchases, and gratuities, though exceptions vary by line, so it's worth checking what's excluded before assuming everything qualifies.
The bottom line
Confirm whether your OBC is refundable or non-refundable as early as possible in the cruise — it determines how urgently you need to spend it down. Book through a travel agent who stacks credit on top of the cruise line's own Wave Season promotions to maximize the total, and track your balance throughout the cruise rather than discovering leftover non-refundable credit on the last night at 10 PM, when it's too late to use.
