Hi Jennifer,
I have to say, your question is making me thirsty. I may be known to plan our trips around the meals so looking at dining menus is one of my favorite things to do! I like your style.
I do believe Jarritos would be included as a beverage option on the
Disney Dining Plan since it is non-alcoholic and not served in a Souvenir Container. That said, I would definitely confirm with your server before you order to be sure. A dinner at
La Cantina de San Angel sounds wonderful right now! I hope you love it.
Also, you always have the option to call (407)WDW-DINE or check out this
helpful FAQ if you have any specific questions about your Disney Dining Plan as you finalize your choices.
Wishing you a delicious dining experience at Walt Disney World, Jennifer. Please let us know if you have any other questions!
