I don't pack drinks because of the weight issue but I wholeheartedly pack one entire suitcase full of food. Our flight is 1 hr. 20 mins so I even freeze meat and take it (wrap it in towels). Perishables are SO expensive in the area because .....well, because they can. I freeze bacon, sausage, steaks, hamburger, hot dogs, precook eggs and freeze them (the price of eggs was ungodly down there), and sandwich meat. It literally saves hundreds of dollars over the course of a week or so.
