I am worried I won't have enough time to defrost the cakes. I freeze all my cakes, but I bake them the weekend before they are needed. The size of the tier will determine how long it takes to defost. A 6 cake will defrost faster than a 16 cake. I would say from my experience I can start working on all the tiers within 1.5hrs from taking them out of the freezer. Now, the larger tiers may still be a little frozen in the middle, but I am fine with that. It makes lifting them easier because they won't break.
