I've read on here that you are not supposed to. However, I do wonder where it's written. I have asked at the parks, when going in, and I asked at our resorts. Everyone seems to think it's fine, and we go right through with some light stuff..P & J sandwiches, crackers, drinks, fruit, and an occasional sub, or leftover from the meal the night before. I have had some of the "searchers" on the way in ask if I could leave it with them for their lunches.
