  19:00Evening free — dinner + wander

  JSNation wraps ~18:10 and the big party was last night, so tonight's open. Grab dinner in Noord near the venue, or ferry back for the canal belt. Early-ish night helps before React Summit tomorrow.

Second conference day at the Kromhouthal, then peel off for the 21:10 Eurostar home from Amsterdam Centraal.

• 🥾
  08:30Check out of Bunk (store bags) → walk to the venue

  Check out before the talks (by 11:00) and stash your bags at Bunk's 24h desk — you'll collect them tonight before the train. Then ~12–15 min walk to De Kromhouthal (same side, no ferry). Badge already collected at the pre-party, so just aim to land ~09:00.

• ✨
  19:30React Summit after-party — ~45–50 min, then leave by 20:20

  Plan: collect your bags from Bunk early (e.g. during the 18:30–19:30 gap after closing) so you can go straight from the party to the station. Party runs 19:30–22:30; with bags already on you, stay ~45–50 min and leave by ~20:20 (20:15 to be safe). No trams in Noord — it's metro 52 (via Noorderpark) or the free IJ ferry, ~20 min either way to Centraal. Hard limit: Eurostar free-exchange ends at 20:10 (1h before), so 20:20 is the latest you can leave without gambling the 21:10.
