Sorry about the title.  I'm about to attack the biggest cake I've done.  I'm going out of town and have to finish it Thursday or Friday morning for a Saturday morning party.

Today is Wednesday.  I am baking and cooking my cakes.  I then plan to freeze them for a bit so they are easier to layer.  I will then frost with a coconut buttercream (Crisco and sugar and extract) freeze until crust and then wrap in saran wrap.  

On Thursday or Friday morning I am going to drizzle with chocolate Grenache and from that point on the cake needs to remain at room temp.  I will deliver to the home and then Saturday the cake will be delivered to the party.

Will this work?  If I freeze everything will that reduce the amount of time it can be left at room temp?

DUPLICATE post.

Won't it go stale? Like unless you can freeze and defrost it fast?

Well sorry ... I don't know how that would have happened.  I only posted once

Grenache?

OP - don't worry about it, it happend frequently.   Just want to alert anyone seeing and posting a reply not knowing there are replies on the other post.
