The ticket page is the truth: look for "21+" or an ID-required note, and assume any bar crawl, nightclub party, or late-night event is 21+ even if unstated. All-ages versions usually run as daytime or early-evening events with "family" in the listing. Mixed venues sometimes flip at 8 or 9 pm, so a legal-but-underage friend needs the exact cutoff time.
Don't try. Instead, name the route order at check-in, set one anchor bar as the regroup point at a fixed time, and start a group thread with live locations. Sub-groups moving at their own pace beat one herd waiting outside every bathroom. Matching costume elements, same hats, same glow color, let you spot your people across a packed room instantly.
Many big parties are no-re-entry or charge again, which matters when your coat, charger, or a smoke break lives outside. Check the policy at the door before you exit, not after, and get the hand stamp verified where re-entry exists. Plan around it: coat check inside, portable charger in a pocket, and the group exits together or not at all.
