You will need to bring enough ice to last until Arctica at Center Camp opens for ice sales — at noon on the Thursday before the event begins. In addition to bringing block ice, you may want to bring frozen food and frozen bottles of water that you can drink as they defrost.
For large projects that arrive more than a week before the event starts, or if you get into a jam, the Art Department can provide you with a limited amount of ice to keep your food coolers cold until you make other arrangements.
