My two are too young for applications yet, but we likely will apply to GDS and Maret, but not Sidwell. I am a GDS alum, my husband is a Maret alum, and we have no edge at Sidwell. We would almost certainly send the kids to one of our alma maters over Sidwell, so there really isn't any reason for us to apply there. Not set in stone, but that is our current thinking.
