Nomad, didn't you read your copy of the rulebook when you moved down here? You tell your guests that Disney is that way and point.

You are doing well to get food in at the house of the mouse, i suppose that since MRE packs don't look like food that they don't notice it. And keep eating away from the crowd so that you won't be noticed other wise you will be politely asked to dispose of your food or you will be escorted off of the premises. Bringing in your own food cuts into the empires profit picture.
