The closest airport is in Muskegon MI (1 hour away), while a more affordable airport is in Grand Rapids MI (1.5 hours away).
Ludington is a beach town. As such there are many AirBnB and VRBO places, as well as several cute BnBs in historic mansions and traditional hotels. We also have three campsites available next to the Rehearsal Dinner location for the adventurous. It may be busy during the holiday weekend so plan ahead.
The closest hotel to the venue is the Stearns Hotel. For lowest prices book through this link or call directly http://www.stearnshotel.com/.
For people coming from the west side of Lake Michigan, there is an overnight car ferry from Manitowoc WI to Ludington which could be interesting.
