You can just tube. I believe you csn bring your own tube but you would need to pay the tubing fee in order to get a wristband to take the bus up the hill
No. You can just tube if you like.
You do not have to camp. You just walk up to the shack, rent your tube, and hop on the bus. Pretty sure you can bring your own tube. I've seen a few large "family" tubes out there.
