Can lemon sponge pies be frozen successfuly

I bought a lemon sponge pie & a coconut sponge pie from the Pennsylvania Dutch. I want to serve them for Thanksgiving dinner one week from today. Can they be frozen or should I just refrigerate them?

I'm not sure what sponge pie is but the following is from the link at the bottom:

Frozen baked angel-food and sponge cakes, when defrosted, are very similar in quality to freshly baked cake. Angel-food cakes seem a little more moist after they have been frozen and thawed. However, both angel-food and sponge cakes are likely to shrink a little in freezer storage. (Angel-food cake made from frozen and defrosted batter is not as fine-grained as cake baked before it is frozen.)
