Wording for Two

Since our wedding will be a two-state, two-celebration affair, I've been struggling with the idea of invitation wording. I want to somehow fit information on both events on one invitation with a combined RSVP card. After browsing countless invitation sites, I've pretty much decided I'm going to have to make the invitations myself because most templates don't allow for that much customization.

When looking around on one of my many favorite wedding blogs, I found the above example from a couple who included their post-wedding party info on the RSVP card. I thought this was an interesting approach. What do you think? Know of any other good ideas for fitting both events into one invitation? I'd love to hear them!
