I brought a backpack and had snacks and put a small cooler in there. Mostly water and 2 Mountain dews. I'm sure it depends on who is checking bags and their mood. It never hurts to try. Food costs on site are outrageous so is give it a shot! They let me through ☺️
The only beverage they allow in the park is unopened water bottles. If you bring in a canister or tumbler it has to be empty
