How to set up chairs for the ceremony and reception!?!?

I have been to a wedding where we sat at the tables and it was fine. Most ceremonies aren't that long anyway. The guests with their back to the altar did have to turn their chairs around, but that was no big deal. It was also nice having a glass of Prosecco to sip on.

If there is room,you can setup a separate ceremony area in what will later become the dance floor, but it's not absolutely necessary.

I've done that before, and having to turn my chair around was no big deal. The ceremony was lovely and then we turned back around and presto! Dinner!
