Hello there Jeven, welcome to planDisney!  
It's always a great idea to make a reservation for a dining package for 
World of Color!  Not only do you get to enjoy a great meal, but it takes the stress out of finding a great viewing area for the show.  
You actually will make a 
dining reservation at either 
Wine Country Trattoria or 
Storytellers Cafe at 
Disney California Adventure Park if you would like the 
World of Color Dining Package.  There are not reservations for the dining package online or via the app, so you can make a Lunch or Dinner reservation for Wine Country Trattoria where guests will receive a prix-fixe meal and a nonalcoholic beverage, or a reservation at Storytellers Cafe for their all-you-care-to-enjoy-buffet for dinner and a nonalcoholic beverage.  
Each guest will receive one voucher for the World of Color Preferred Viewing Area (the viewing area is separate from the dining location), and you will need to let your host or server know at the restaurant that you would like the World of Color Dining Package.  The dining packages are available on a first-come, first-served basis, and are subject to availability.  Each guest will also need a valid 
theme park ticket and 
theme park reservation for Disney California Adventure Park for the same date.  
Depending on when you visit Jeven, you may even get to experience the new 
World of Color - ONE show that is part of the 
Disney100 Celebration!  It's such a wonderful compilation of our favorite Disney characters and movies, and the added scenes from Star Wars and Marvel put it over the top for me!  
I hope this information was helpful for your trip later this summer!  If you think of any other questions, please do not hesitate to 
come back and ask!
Have a magical day!
Melissa
