Wedding Reception Games/Ideas

Hello, I am getting married on 7/7/07, we both have been married before so we are having a casual midnight ceremony with family and friendsthe reception is 1st then the ceremony at midnight- money is tight so we will not have a DJ, just a mix of CDs, I am in a wheelchair- he is not, I`m looking for things/games to do that will involve/occupy the kids w/o making it a kids party and to keep guests mingling-entertained until the ceremony.
