Just about anything that isn't in glass EXCEPT no adult beverages!!
16 Oz water bottle, you can take food but not in any glass containers. They have a picnic area on the left side were you can eat after the shuttle drops you off. Baby food can be taken with you. They also have lockers for rent.
We took an empty water bottle and general snacks we bought. Chips, granola bars, nuts, cheese and crackers, jerky and fruit, and fruit roll ups. Things like that. We also took our Disney refillable cup. We put it in our backpacks
We took a small string back pack with bottled water, sandwiches, and chips. Our daughter has food allergies to dairy and wheat. So there was not much she could eat except fruit and fries.
We walked in with 2 open rockstars, a hydroflask of water, sandwiches, string cheese, apples and more. No problems or questions from security. Other than alcohol, all snacks and liquids are good to go (within reason though, I suppose).
