My fiance and I wanted to include the people we work with in our special day but we only wanted to invite them, not their significant others and families. I addressed the invites with just their name. Etiquette that I understand is the people listed on the invite are the only people invited. I received some RSVP that include 2-3 guests for every 1 that I invited. We are on a very tight/small budget and we really can't afford any extras. I want to explain this to them and tell them they have to leave their families at home but I don't want to come off insensitive and rude. How do I talk to them or should I just let it go?
