Are we allowed to take snacks and water inside the park.

Yes its allowed no glass containers tho

Bring a thermal bag or lunch box, remember that it is very hot

Yeah they have to be in a bag

We had chips and water bottles with us month ago and they let us take them in.

Yes, you can bring food and drinks. You can also bring a handheld cooler but no large coolers with wheels.

There's a policy online somewhere that states what you can bring. But I'm pretty sure if it's not something dangerous you can bring water and food.

Yes
