It's in the Mckintrick Hotel right near there. Actually not a hotel at all - a fake hotel they created inside the multiple warehouse complex that hosts the set/event. But if you google maps that hotel it comes up.
As for tickets, I'd just keep an eye out on the official site or this close SH. They prob come up a lot even though it's been sold out for years... scalpers/SH prob charging north of 300 when they do come up.
I think you can just go to the "hotel" bar without tickets. It's pretty cool itself.
