Hi, I am getting married in Florida, we decided to have a extremely small wedding, the guest list is bride, mother, father. Groom: mother, father&stepmother. We told them about the arrangements we had made and would love for them to make it. But..... Stepdad assumed all the brothers an sisters were invited too and wants to turn it into a half paid for vacation.. This is getting to big if all the brothers and sisters on both sides come. How do I politely tell them no.
