Our family (grandparents, parents, and 4 children aged 9-17) had a lovely stay! We loved the ability to balance our time indoors and out. We were close enough to Manistee to visit local shops downtown for any needs as well as close enough to Sleeping Bear Dunes to make the day trip out.
For planning, we found parking at the bottom of the hill and walking up to be best for our group. It's a pretty steep incline going up and down, so that was the best option for us and our vehicle. That does mean a lot of stairs (as you can see in the photos), so plan in advance if your party has any issues with stairs. Our family was quite comfortable and would absolutely love to come again.
