Well I took the Jello no-bake and made it with Parkay just as MuleLars described. I had a round Tupperware container that I was using to store some spices in that I put the pan in when I set it in the water to cool. Didn't have to worry about water getting in, or about keeping it shaded since we only saw the sun for a couple of hours the whole week. The cheesecake was a huge hit. It will definitely be on the menu on all future trips.
