Hey howdy hey, Jeri!
Welcome to planDisney and thanks for stopping by with a fantastic 
Walt Disney World Resort vacation planning question. 
Yeeeeee-haw! It's almost time for your exciting adventure to The Most Magical Place on Earth. As you gear up to embark on your thrilling journey, I'd be happy to help you finalize your packing list before you saddle up and head out!
Sheriff Woody would advise that before Guests visit a Walt Disney World Resort theme park, they should refer to the 
property rules. Not only do these rules include a list of prohibited items, but they also provide guidance on acceptable bag sizes! I'm happy to inform you that bags up to 24" long x 15" wide x 18" tall (61 cm x 38 cm x 46 cm) should be permitted into 
Disney's Hollywood Studios and other Walt Disney World Resort theme parks. Jeri, of course, all Guests and their items are subject to security screening before entering a theme park, and, ultimately, items permitted are based on security Cast Members' discretion.
Once you and your backpack are inside Disney's Hollywood Studios, be sure to spend some time in Andy's backyard - in 
Toy Story Land! This area is sure to bring out your inner "kid," shrinking you down to toy size and immersing you in Disney magic. Stop by 
Woody's Lunch Box for a delicious Lunch Box Tart: the perfect sweet snack for any time of day or night! Finally, don't miss 
Fantasmic! to cap off your exciting day in the theme park. Of all the fantastic nighttime spectaculars at The Most Magical Place on Earth, this one's my favorite. The finale makes me emotional every time!
Jeri, I hope this information helps you get started on your journey to the Walt Disney World Resort, and I wish your travel party the rootin'est tootin'est time! If you have any more planning questions, feel free to stop back by 
planDisney again anytime. We're here to answer 
all of your questions about your Walt Disney World Resort vacations - to infinity and beyond!
So long partner,
Lauren
