I am a great fan of disposable aluminum trays and pans. I usually take the largre ones and fill partially with hot water sitting on bricks to support and liquid heat below for hot items then place my smaller trays in them with aluminum foil to cover large pan vented away from guest. And same idea only with ice in larger tray. After the party I throw them away. Now this usually occurs when doing a gathering away from home so after the oven gets built this idea may change.
