Hi Thomas.
Thanks for visiting the Moms Panel with your question.
I have seen the Power Pack Lunch of 'snacks' available over at Fairfax Fare at Disney's Hollywood Studios, as well as at Pizza Planet, Rosie's All American Cafe, Backlot Express and ABC Commissary (all at Hollywood Studios).
Unfortunately, I've yet to see it listed as a menu option over at any Quick Service Dining Locations in Magic Kingdom Park, Epcot or Animal Kingdom. Let's hope this great box of "healthy munchies" makes its way onto some menus at the other parks soon!
If you're looking for some healthy snacks to pick up during your day at Magic Kingdom, a great, new spot to be sure to check out is
Prince Eric's Village Market. It's located in the New Fantasyland area of the park near the exit from Ariel's Grotto. I've included a link to the menu for you just above.
I hope this information is helpful to you Thomas. If you have more questions, please feel free to visit me again any time! I'd love to hear from you again.
Wishing you a simply Magical time at Walt Disney World!
Kirsten
