Hello all i need some help my husband to be has a very big family and most of them wont be coming to our wedding and i like the save the date cards is it tacky to put a rsvp on them because the place we want to get married we can afford for them to all come but if we know that like half the people aren't coming we will have more money to spend on other things , i am so stressed out about this because i don't want to be tacky but i also don't want to have to spend an extra 100 on invites just to some people are happy they got one but are not coming and his mom said that most of them wont respond which is rude and a waste of paper.
