Telling family

Looking for advice. My fiancé and I are planning to elope this coming March. We have not told my family, with the exception of my sister. I’m trying to think of when/how to tell them all. My parents are divorced so the only time we are all really together are the holidays. The next one after that would be Easter. Should I do it then? I fear if we tell them ahead of time, we will get people trying to invite themselves along with the added stress on the trip with a million and one questions of “what flight are you on? Where are you staying?” And so on. Regardless I think my parents will be overly dramatic about it and probably upset they were not there.

We do plan to have a small dinner after the fact to help give them the event around our wedding that they are looking for.

Long story short, they are going to be upset and over the top about anyway we tell them. Just looking for ideas ms advice!
