You can take certain things, chips, a few small sandwiches, bottled water, chopped fruits (small amount) are not as strict as in Aquatica but still if they check but mostly in search of weapons. If you place everything discreetly there will be no major problem
Nobody checks the backpacks or bags if you carry, supposedly it should not be like in the rest of the parks, but if nobody checks maybe you can take something light
