 - **~5:50 PM** El Capitan Meadow on the way out — face lit from the west; 15-min stop. Northside Drive is one-way west, so there is no second pass. Two pullouts beside the meadow, in driving order: [east end](https://www.google.com/maps/search/?api=1&query=37.72708,-119.63033) (by the El Capitan Drive crossover) and [west end](https://www.google.com/maps/search/?api=1&query=37.72453,-119.64089). The [El Capitan Picnic Area](https://www.google.com/maps/search/?api=1&query=37.72818,-119.62057) is *before* the meadow. If both pullouts are full: continue over Pohono Bridge, east on Southside Drive, stop at [Cathedral Beach Picnic Area](https://www.google.com/maps/search/?api=1&query=37.72292,-119.62438) (El Capitan across the river), then left at the El Capitan Crossover back onto Northside Drive — ~20 min extra. Do not loop for the picnic area; that is ~40 min
 - **~6:15 PM** [Valley View](https://www.google.com/maps/search/?api=1&query=37.71728,-119.66187), a few minutes further on, just before Pohono Bridge; small lot at the viewpoint, 10-min stop
 - **~6:35 PM** [Tunnel View](https://www.google.com/maps/search/?api=1&query=37.71557,-119.67689) — arrive 20 min before the ~6:55 PM sunset; lots on both sides

+- **~7:45 PM** Wawona check-in — Hwy 41 south ~40 min, then right on Chilnualna Falls Road at the Wawona store, ~2 min to North Wawona. Verify the Booking.com PIN (`4317` in the Sep 18 email vs `5937` in the saved confirmation) before leaving coverage; the property door code remains `0517`.

+## Reconciliation
+
+- The arrival request is already answered in the Booking.com chat: estimated arrival approximately 20:00 PDT on 2026-09-22.
+- **Open discrepancy:** this email lists Booking.com PIN `4317`, while the existing booking record and saved confirmation list PIN `5937`. This is distinct from the property door code `0517`. Verify the Booking.com PIN before arrival; no value was replaced based on this email alone.
