I'm always so conflicted about national parks. The idea to make things more accessible by building tons of roads through it kind of ruin the beauty of the place for me.
It is a really spectacular place. Ditch the car and take a hike and you'll find some peaceful places you wouldn't see otherwise.
While the weather wasn't ideal...it's still totally worth a gander. Get up early to watch the sun rise from the top of Cadillac.
