Do you have to set up an appt after you purchase your ticket? Or do you just show up from 1pm-9pm to do your walk through?

We were lucky to be there at 1pm. But the line filled up quickly.

just show up but wait is about a hour

Just show up.

They usually take 10 people per group you go inside buy your ticket go on tour it's an hour and 15 min

Whether you purchase your tickets online or at the door, you have to wait outside for a tour. We waited about an hour and a half to get in. And there was only 2 groups ahead of us. 20 people ahead of us. But so worth the wait.

Just show up. Or you can get tickets online. No appt. First come, first served. We waited about 90 minutes.

You will purchase tickets for a certain time... they have you come early to get stoned.
