After meeting with our Wedding Production Director yesterday, he mentioned that we may need to shave off about 20 people on our guest list. We are spending alot on the DJ services, special effect, lighting, and etc. We want a pretty decent sized dance floor. But in order for us to have room in our venue, we need to remove people from our invitation list. We are sending wedding invitations next week but we sent out Save The Dates a few months ago. Would it be wrong if we don't send out wedding invitations to some people who received our Save The Dates? How should I handle this? Please help...
