Timed entry is a valve on a crowded building.

I am not selling tickets. I am telling you how the door behaves so you do not arrive angry at a dark phone. No prices on this page.

What an e-ticket is

An e-ticket is a record that a named slot exists for a set of guests. It usually lives on a phone as a QR code, or as paper of the same code. It is not a metal token and it is not a debate. Brightness up. Screenshot that actually scans. If the battery dies in the Union Station concourse, you have a problem I cannot fix from a P.O. box.

Why slots exist

The shark tunnel is a belt with a width. The jellyfish gallery is a room with a door. Timed entry exists because an open door at Saturday noon would stack the lobby into the sidewalk. A slot spreads bodies. It does not promise an empty tunnel. It promises you may join the line during a window.

At the door

You present the QR code. A scanner accepts it or it does not. Wrong date, wrong window, party size that does not match — those are the usual failures. Staff can sometimes move you. Sometimes they cannot. Build slack if you walked from Union and the slot is tight.

This guide does not issue tickets, hold inventory, or take payment. If an advertisement implied a checkout on these pages, it was wrong. See FAQ and Privacy.
