Hi Emma and welcome back!
Here at the Disney Parks Moms Panel, there is no such thing as a silly question! You can absolutely purchase your theme park ticket at Disney's Hollywood Studios. There are ticket windows outside the park when you arrive. If you want to save some time, you can
purchase your tickets in advance.
Since you're visiting Disney's Hollywood Studios, I highly recommend you pay a visit to the newly opened
Toy Story Land. You will truly feel like you've entered Andy's backyard.
Alien Swirling Saucers is great fun, spinning around space to out of this world tunes.
Slinky Dog Dash is a speedy romp up, down, and all-around Andy's backyard. Hopefully, you can enjoy these fun, new attractions before you head to the Magic Kingdom Park to enjoy more favorites.
Emma, thank you for visiting us again. I hope you'll let us know if you have any more questions!
Wishing you a magical vacation,
Amy H.
