Hi Marcela,
Walt Disney World is the most magical place on earth. I'm so pleased you'll be able to visit this coming spring.
Free dining promotions allow guests who book theme park tickets and a Disney resort room the opportunity to enjoy a set number of free snacks and meals per day during their stay at Walt Disney World. These are very popular promotions but, unfortunately, we never know for certain when they might be offered. The current offer for free dining is posted
here. Be sure to visit the "special offers" page on the disneyworld.com website often to see if new promotions covering your dates of travel have been released.
If you are lucky enough to qualify for free dining, that's awesome! All you need to do when you dine at Walt Disney World is present your Key to the World card (room key) to the Cast Member serving you and let them know you'd like to pay for your meal with a Disney Dining Plan credit. They will simply deduct a credit from the total number of credits on your account to pay for your meal. I love using the Disney Dining Plan! It is easy and cost-effective.
Please don't hesitate to post additional questions regarding the Disney Dining Plan if you have any. We'd be happy to assist you.
Best wishes for a magical vacation!
Jill
