Hi, Deonna! Thanks for bringing your question to planDisney!
Yum! It's almost lunchtime when I'm writing this and now I have a hankering for a turkey leg!
You can definitely bring some storage bags or foil with you to the parks to package your leftovers. I have found this helpful in the past when my child wants to save part of her snack or dinner for a later time. The only type of storage material that's prohibited are glass containers.
Keep in mind that there are
rules around bringing coolers into the Disneyland Resort if you were planning on keeping things cold. Coolers should be no larger than a six-pack and loose ice is not permitted. So plan on bringing some cooling packs if you intend to bring a cooler. You can also
rent a locker to store the cooler if you wish.
Also, if you'll be staying at a
Disneyland Resort Hotel, you might want to hop back to your room to store your food in the mini-fridge. There are also microwaves located in common areas of each hotel that you can use to reheat your food. Just check with a Cast Member at your hotel to locate the microwaves.
I hope this helps! Have a great time at the Disneyland Resort!
