Jennifer,
I completely understand! When I planned our first trip this was the hardest thing for me as well, but now I have it down to a science.
The first thing I recommend is visiting the
calendar page. You will be able to select the month you need to see, and view each park schedule individually. From there you can click on each date for a breakdown of parade and show times, as well as Extra Magic Hours (EMH) for resort guests.
I like to map out our itinerary first; it's easier to know where to eat when you know where you'll be. If you are buying park hopper tickets then take that into consideration and time your meals to coincide with events you want to catch in each park. We like to eat at resort restaurants as well, so it's convenient to plan a meal near the park you want to visit.
Finally, make sure you allow enough travel time to get from the park or resort to the restaurant. It's best to arrive 10-15 minutes early so you can be seated close to your original reservation time.
Happy feasting!
