I appreciate your suggestions!
I really get the feeling from SAS that they will not do that ... I have a good feeling about them. I think they will do the announcing but then keep their mouths quiet and let the music do the entertaining.
As far as lighting, I posted the same question about a week ago so you can see some of the responses that came in. They just say that lighting is conducive to danicing. I am having only white lighting as opposed to color lighting. I am doing minimal lighting as opposed to intelligent lighting (from what I hear that is for really big parties). It was way too much.
I never noticed lighting at the past weddings I went to, but from talking to people most people who have an evening wedding get the basic lighting package.
As of today I should be all booked!
Good Luck!
