If a trip to a Disney World restaurant is on your list of things to do on your Orlando vacation, you’ll need to make note of the new reservations policy announced this week. Changes to the cancellation policy could end up costing you extra money on your next Orlando vacation if you don’t follow the new guidelines.

As of October 26, 2011, you’ll need to provide Disney with a credit card number when you book your reservation at select dining locations. Your card won’t be charged until you dine, unless you don’t show up or cancel in time.

You’ll be charged a $10 no-show fee for each member of your party if you skip out on your reservation, unless you cancel it in advance. According to the Disney Dining reservations specialists, you’ll need to contact Disney and cancel your dining reservation at least 24 hours in advance; so show up on time or pay a hefty fine.

Not all Disney restaurants are affected by this change, but most of the popular dining locations are. Disney World restaurants covered by the new rules include character dining spots like Hollywood & Vine and Chef Mickey’s,  resort headliners like Artist Point and the California Grill and Epcot’s popular Le Cellier.

Some signature Disney dining locations, including Cinderella’s Royal Table in the Magic Kingdom and the Hoop de Doo Revue already charge the entire dining fee for no shows. These locations will continue to do so and are not affected by the current changes.

So what do you do if you change your mind? Instead of simply not showing up, you’ll need to cancel your dining reservation. You can cancel by calling the dining reservation line, visiting your resort concierge, stopping by theme park guest services or going to the check in podium of any table service dining location. Cancel your reservation 24 hours in advance to avoid the new dining fees.
