There are multiple stops some will have parking
Free parking if you buy tickets
I go to the parking garage and put my car there. You can buy tickets in the visitors building next to the garage. And the troll will pick you up out side.
Yes. There are several places you can pick up the tour and most have adequate parking. You are able to get off and do your sightseeing and then get back on and continue the tour. You can pick up discounted tickets from the kiosks that include multiple days.
