Travel
There is a limited block of rooms at the Cherry Tree Inn and Suites on the edge of East Grand Traverse Bay (the north end of the main drag in TC) that may have a shuttle running to and from the wedding, covid pending. This hotel is ~5 minutes from Cherry Capital Airport and there is a free shuttle. There are cars for rent at the airport. There are a somewhat limited number of uber/lyft/taxi drivers in the area, but it can be done!
I would recommend getting lodging ASAP because of the memorial weekend surge!
