As a former wedding director/coordinator and photographer ---- favors are not needed and more often than not the guests don't take them home anyway. They don't look around at the reception and say "WELL! where are the favors for US to take home?" They look around and enjoy the precious time of celebrating the joy of your union and that fact that they are part of what will be a wonderful marriage and life together.
It is your day, plan, relax, enjoy and don't worry about the little things.
Oh, and congrats to you and yours!
