For the Disney Princess Breakfast Adventures at Disney's Grand Californian Hotel (Disneyland Resort) or similar experiences at Walt Disney World, you can book up to 60 days in advance. In 2026, the booking window typically opens at 6:00 AM Pacific Time (for California) or Eastern Time (for Florida) daily. For guests staying at a Disney Resort hotel, there is an added advantage: you can book for your entire stay (up to 10 days) starting 60 days from your check-in date, which effectively allows you to book up to 70 days in advance for the latter part of your trip. These character dining experiences are among the most popular in the parks and often sell out within minutes of the window opening. It is highly recommended to have your "MyDisney" account set up with a credit card on file before the 60-day mark to ensure a fast checkout. If you miss the window, you can check for "Day-of" cancellations via the app, which often pop up due to Disney's 24-hour cancellation policy.
