Multi-venue Invitations

You do one rsvp. Everyone's invited to both so they only need to rsvp once. This is normal lots of people have church weddings and then a reception elsewhere. You just indicate ceremony at location and then reception at location on both your detail card and website.

I'm doing the same and I will have a event detail card with my invitations having the reception locations address and time stated! I'll put my wedding website URL there as well and inform them how to RSVP using the site.

Ceremony location on the front/main portion of the invite

Reception location under details or on details card accompanying the invite.

One RSVP as all guests attending the ceremony would likely want to the reception as they were invited to both events.

They only need to rsvp once for the whole thing. It's one event. I've never heard of people going to the reception who didn't attend the ceremony. However at my husbands cousins wedding, my MIL went to the ceremony and then went home and didn't go to thr reception which I thought was rude since she did rsvp and they had a seat reserved for her.

This is the same as we had too. We did the insert card with the reception information on it. Sad to say that some people don't attend your ceremony and only the reception. Seriously an asshole gesture.

We are saying:

"XX and XX joyfully request your presence at their wedding"

Date

Time

Church Name

"Cocktails, dinner and dancing immediately following at:"

Reception Venue Name

The information card has the addresses of both venues, as well as our website, hotel info, etc.

People are essentially RSVPing for the reception, not the ceremony. My mom claims "no one comes to the ceremony because no one cares" but that's not true. You may have a handful of people that can't make it because of work, kids, etc. but plan on everyone for both events.

ETA: I was afraid that if we didn't put the reception venue name on the card that people would think the whole thing was at the church. I don't know why that's a fear of mine but it is. Traditionally, only the ceremony information goes on the invite, so I know I'm going against the norm. I was just more comfortable that way.

Keep both on a card whether that's one detail themed card or the invite. Also, update your wedding website to provide excellent directions. Most people will loose or forget the invite.
