Hi Eileen!
Thank you for visiting the Moms Panel!
The calendars for each Walt Disney World theme park are usually published around six months in advance, so should coincide with when you are able to make your advance dining reservations. I agree, when planning, the two go hand-in-hand, theme park schedules and dining opportunities.
I have provided inks to the calendars below, and I would recommend you begin checking for the November schedules beginning of May.
Magic Kingdom Epcot Hollywood Studios Animal Kingdom
Don't forget to pick up a copy of the Times Guide as you enter the park, for that day's most up-to-date entertainment schedule.
If you have any more questions, please come back and ask me - I would be happy to help you plan your magical vacation!
