My FH and I decided last week to get married while on vacation at the beach in March. It will be us, my daughter, and a friend sharing expenses of the rental. Our budget is very limited so we thought about having a party, a few weekends after, with immediate family members but doing a potluck and having them include the recipe for us to start our own recipe book. We know they will be fine with this, but should we send out an invitation or just tell them? How could I word it nicely if I do go with the invitation?
