**If you are wishing to have a BIG beautiful cake but don't want to have that many servings then an option you may choose is to have foam "dummy" cakes. For example, you may want a 6 tier cake but only need to serve 100 people. The solution is to have some of the tiers be decorated foam. Your guests will never know and the cake will stay as a centerpiece throughout the reception!!
