I am making a wedding cake in a few days. I want to bake ahead. I would like to try the press and seal method - wrap hot cake in press and seal, freeze, set out 10 minutes before unwrapping. My question is when can I torte the layers? Layers need to be frozen to cut. If I let the cake set out before I unwrap and cut the layers, the cake will be too soft to get a smooth cut. So, how do I do this???

You want to "try" a new method on a wedding cake?

If I were you, I would try that method on a small cake (same recipe as wedding cake) and see if the results meet your expectations (rather than risk wasting all that time baking and ruining your cakes).

Here the post that details the method you want to try:

Yes just as JanH said, test it before, you don't want to have a bad surprise
