We bring our 12 X 11 x 9 Coleman 9 quart insulated cooler on every cruise. We love to keep our waters, sodas and beers ice cold for enjoying on our balcony.. It wont leak and you can keep it right on your counter. We put our drinks in it and our steward always ices it up for us. I carry it onboard, filled with nuts, crackers, protein bars, snacks, etc. We even take it with us if we visit a beach while in port with some ice cold drinks. Any of the bars will ice it up for you too.
