Arriving at that time in the morning I would certainly put some basics in my suitcase, favourite cereals, maybe the little selection packs, some sachets of powdered milk, tea bags, coffee, and some of the sauce sachets available in most restaurants. We always take favourite biscuits and cheese kept in the fridge at home until just before we leave, I know a lot of people take bacon, sausages and even butter. The Sunday market is open all day on Sunday and you can pick up fabulous fruit, veg. and most of your other requirements there. Other things are readily available at any of the many supermarkets, which are all open on Sundays.
