We ended up deciding on Chicago for the weekend in August (now need to find acceptable accommodations) but we are also going to Traverse City for the July 4th weekend. Sleeping Bear was what put TC over the top, compared to other locations.
Not much award night availability, unfortunately (serves us right to wait until two weeks before traveling on a major holiday weekend), so I had to bite the bullet and book the Holiday Inn Acme/Traverse City for 35K/night.
