Our site overlooked Mackinac Bridge which was beautiful at night. The place has shuttles to the ferries and you can pre-purchase tickets. Good amenities and the dump area is efficient and clean.
Only negative is the firetruck that goes by every 15min that the kids love but we hated the siren and bells while we were trying to relax by the fire.
They rent bikes which I'd encourage to see the area and to ride to the historic mill.
I've stayed there twice and definitely will again!
