Most foods and drinks are very expensive, especialy if you are not American and you have to exchange your hard earned money to US funds. I recommend you bringing snacks and drinks or cold water in bottles. Leave the cooler in you car and when you get hungry you just go out to your car to eat and drink. Security will place a stamp on your hand so you can re-enter into the park.

Unique Suggestions: Bring your own foods and drinks.
Fun Alternatives: Eat before you leave.
