Should I skip merch to guarantee entry?

If your ticket is tight on time or you have accessibility needs, yes — merch often restocks online later.

How early is too early?

Overnight camping is often banned; follow the venue’s overnight/queue notice.

T‑6 to T‑3 hours: Merch booths often open early; limited drops sell out — decide merch-first vs seat-first.
T‑2 to T‑1: Bag check and security peak; clear liquids/power-bank rules from the venue PDF.
Show + encore: Expect staggered exits; agree on a meetup pin outside the crush.
After: Subway last trains in Seoul are unforgiving — screenshot the route before encore lights.
