We highly recommend the Grand Rapids Airport (GRR) as its a 10 min drive from the Venue. While Detroit (DTW) is the bigger airport, it is over a 2 hour drive away and will require a rent a car.
The Wedding is at 3232 Shaffer Ave SE, Grand Rapids, MI 49512
We recommend checking out Frederik Meijer Gardens & Sculpture Park at 1000 E Beltline Ave NE, Grand Rapids, MI 49525
If you fly into GRR and only plan to stay one night, Uber/Taxi would be the cheaper option. Airport -> Hotel, Hotel -> Venue, Venue-> Hotel, Hotel -> Airport. All are within 10 min of each other. (Bob is working to get a shuttle from the Venue to Tru Hilton hotel, so ask him about it!)
