The closest mid-size airport is in Grand Rapids, but Traverse City also has its own airport that you may choose to fly into. If you choose to fly into Grand Rapids, Traverse City is about a two-hour drive away. Allegiant flies direct from Jacksonville to Grand Rapids and from Sanford/Orlando to Traverse City, but offers a limited schedule.
If you're flying into Traverse City, you can get away with not renting a car - Uber and Lyft are pretty reliable in the summer months, and there is plenty to do in Traverse City to occupy your time. But if you want to venture out to see more beyond Traverse City, we highly recommend renting a car versus relying on ride share alone.
The sooner the better! Northern Michigan is a very popular destination in the summer, and hotels book up quickly, as do AirBnBs if you're considering going that route.
Transportation will be provided for Saturday's beer and wine tour, as well as for the ceremony/reception/after party. Guests will be picked up from the two wedding hotels.
The dress code is formal. For women, think midi or floor-length dresses, jumpsuits, etc. For men, suits or slacks with a blazer and tie.
