While we'd rather keep it to adults-only, we know many of our friends and family cannot get a sitter. Or your sitter has been invited to the wedding. So bring them - we'd rather have you there with your kids, then miss our wedding and reception.
Probably Not Erie International Airport. Single airline only to Charlotte. Our favorite is Buffalo as it's easiest to get in/out of, but Pittsburgh and Cleveland are about the same distance with great accessibility. Plan on about 90mins of highway driving.
