No dress code you need to stress about, no complicated entry. Show up in the window, sign your name, and settle in. Here's everything else.
The entrance is quick, and it's a small ritual. Everyone does it the same way.
There is no single camera rule across every event. Yours is stated on the listing, at checkout, in your confirmation and reminder, and on the envelope you get at the door — and the ticket and envelope are the ones that decide. A phone-free night tells you before you arrive so you can plan.
The same rules, put plainly for the door.
