I would call ahead to just make sure they aren't at capacity
You can get the app and it can tell you what days they are open and wether they are at or near capacity. You need to reserve your spot.
Yes
Call to be safe.
I went on line and reserved ours. We went the Saturday after Thanksgiving so knew it would be busy and it was.
We got ours threw where we were staying at they went on line and printed them out
They are open, so I'm sure they will be selling tickets at the gates.
