Autopilot a must - you didn't say. Otherwise I would have no problem. Are you anchoring at Round Lake or going into Lake Charlevoix? I wouldn't want to try and anchor in Round Lake after a long sail in the dark. Too deep (90+ feet) and too many boats anchored in too small an area.
Be sure and have someone on shore that you can call and give updates on your position at regular intervals.
I would make sure I had a good harness/life jacket like SOSpenders and tether myself to a jack line. You can never be knocked or fall off the boat.
