Disney Cruise Line has evaluated and adjusted the onboard sales booking offer. Guests who book a future cruise while onboard a Disney Cruise Line ship will receive the following benefits: â€¢ 10% off prevailing rates (as quoted on disneycruise.com) â€¢ Up to US $200 onboard credit per stateroom â€¢ Reduced deposit on sailings 7-nights or longer With this change, Guests who book onboard must complete travel within 18 months in order to maintain these benefits. Guests who are unable to sail within this time period will have any current onboard booking benefits removed from their reservation. Guests can modify their sailing dates within this 18-month timeframe as long as these modifications are done outside of any applicable cancellation period. This change will also apply to Guests with an existing reservation made onboard; however, Guests with an existing reservation will have an additional six-month extension and will need to sail prior to Nov. 30, 2015 in order to keep their onboard booking benefits.
