Cream Cheese Frosting at Room Temperature under Satin Ice

by JoAnne

I know that fondant should not be refrigerated. If I put satin ice on the outside of a cake that has been crumb
coated with cream cheese frosting, how long will the frosting keep under the satin ice at room temperature before it is not safe to eat? At the bake shop where I purchased the satin ice, I was told that fillings with eggs in them, the cake, etc. would keep just fine for several days without being refrigerated, but they didn't know about the cream cheese frosting under the satin ice.
It would be ideal if I could keep this cake at room temperature for about forty-eight hours before serving it.
Would this be safe or not?

Thank you so much. Anxiously awaiting your answer.
