So my venue is priced per person, the price we all agreed upon was for 50 people so I'm like that's cool, I don't really want more than 50 people... As I'm filling out RSVP cards, I'm feeling the need to say "no +1 unless indicated, and no kids". The more I think about it, the more I think this single people or families who are invited may be upset or offended. Basically I'd love for people to invite +1 if all my family is given the opportunity to come but some may not be able and the total guest count is under 50. So what's a good way to say, "you can bring a +1 if all of my family that is able to come is accounted for and there's space available but "no kids" is non-negotiable". Please help me be polite, haha.
