Hi Angela,
  Thanks for visiting Disney Parks Moms Panel and bringing us your question. 
 I hope you are looking forward to your trip to 
Walt Disney World! There are so many new and exciting attractions this year and this is a great year to visit! 
 Yes, you can bring your own lunches into the parks. My family and I often pack a bag with our own lunches and snacks and beverages to enjoy throughout the day. 
Tom Sawyer Island is a favorite hide-away for us to venture off and enjoy a quiet lunch in the shade. We also enjoy picking a quiet spot along Main Street, U.S.A. to enjoy our lunch and simply take in all the magic. 
 Keep  in mind, you will need to take your packed lunches through a 
bag check before entering the park. Be sure your packed lunches don’t contain any glass containers as those would be prohibited.  
 Enjoy your magic picnics! 
 Jerry
