I am definitely worried about it too! I invited 100 people to our wedding and thought we would have 60 attend, but it looks like it will be about 38, plus some kids. I've been a little upset over it and have had thoughts about whether I should have done a local wedding, but I know it will be an amazing time. I think the key to getting people to dance is having GREAT music and lots of alcohol. Unfortunately, the only thing we can do is plan the music list and hope for the best. I have never heard anyone say they had a bad time at a destination wedding, but I have heard people say local, traditional weddings, have been just okay!
