In a couple weeks, I'm having a surprise party for my husband at a park. I am ordering large meat/cheese trays and I want to be able to keep them cold. The trays are a heavy duty plastic (I'm getting them from Sam's Club). Does anyone have any ideas of how to keep them cold? They are too big to fit in a cooler.
