This park is right across from the church, and weather dependent, could be a nice place for a stroll between the events.
A cute little cider mill a short drive from the church.
A cute little spot to stop in for some coffee if you want to go more local than the Lapeer Starbucks.
A wonderful all-organic coffee shop located near the venue, just note they close at 3 so you would need to head straight there after the ceremony
This park is off the highway between the two venues and has a decent walking trail, depending on what level of fancy attire you have chosen for the day.
