Dear Karla,
Step away from the books. And breathe. Ahhhhhh, isn't that better?
Now remind yourself: Disney is the happiest place on Earth! That's why you are going!
There are so many great places to eat at Disney World. So I would first recommend taking a look at the various restaurants
online. You can browse them by cuisine, location, and dining experience.
Once you have a feel for which restaurants you might want to visit, think about your child's typical day. In my experience, my family only dines at one table service restaurant each day. For us, we either start the day with a sit down breakfast or end the day with a nice dinner. This way we've "planned" but not
over planned. For lunch, my family grabs a quick bite to eat in between attractions at one of the many counter service restaurants in the Theme Parks.
One last suggestion is to take a cue from your little one. If you find your child is tired, feel free to lounge by the pool that evening instead of eating out. No one will take away your Mickey ears because of it.
Good luck. And happy eating!
