We always take on the Moccona cappuccino satchels as the coffee out of the machines is horrible, plenty of hot water to be had. There is iced water & glasses at every bar to help yourself. You are allowed to take on cans of soft drink or non alcohol beer. I take on a Brita water bottle to fill in my cabin, the water is drinkable I just don't like to. If you like chips, nuts or lollies take them with you as why pay ship prices for them unless you have to.
