Group packages. One purchase, four people

A group package is a tier with a package size. One purchase admits that many people and issues that many tickets, each with its own code, so the group can arrive separately.

Packages sit outside the ladder: they stay on sale while the tiers open in order, so a table of four can buy at any point in the night's pricing.

Quantity on a package is counted in packages, not people. Ten packages of four is forty admissions, and the event's capacity counts the forty.
