Guests looking to book a cruise or access a reservation through Disney Cruise Line need to know that the system will be unavailable due to routine maintenance for a day in July.
Reservation System Maintenance

If you visit the Disney Cruise Line website, a notice pops up indicating the upcoming system maintenance. It will take effect starting at 4 a.m. EST on Thursday, July 9, and end the following day at 4 a.m. EST on July 10.
During this time, guests won’t be able to make or access reservations online or by phone. If you have a deposit or final payment due during the maintenance period, the payment will be due on July 11 by 10 p.m. EST.
