Hi Heather,
The times at which Lunch and Dinner are served varies from restaurant to restaurant.
You can check the times for your particular restaurant by following these steps:-
1/ Visit the Walt Disney World website
2/ Click on WHERE TO EAT at the top of the home page
3/Click on Make Dining Reservations
4/ Where it says 'Enter a Restaurant Name', type in the name of the restaurant where you have made your
Candlelight Dining Package followed by 'Search for a Table' (The Date, Time & Party Size boxes are irrelevant)
5/ You should now be taken to the Make A Reservation tab for that particular restaurant where you will see the times that Lunch and Dinner are served.
If you have any problems at all, please ask me another question detailing the restaurant where you have made your dining reservation.
Wishing you a magical trip filled with memories which will last a lifetime!
