Reading Ferry Manifests Alongside Hotel Pickups

Harbour hotels along Yeosu's Odongdo corridor often receive two distinct arrival pulses on summer Thursdays: a mid-morning ferry cohort and a late-afternoon secondary wave tied to same-day rail connections from Suncheon. When revenue teams treat hotel pickup counts as unrelated to pier tallies, breakfast and shuttle rosters drift out of sync.

We overlay anonymized manifest summaries—aggregated to the hour—with front-desk check-in timestamps supplied by participating properties. The resulting plate shows a predictable ninety-minute lag on peak weeks. Properties that shifted prep rather than adding seats reported shorter lobby queues without increasing food waste.

This method depends on willing partners sharing timestamp exports under confidentiality, plus licensed ferry statistics. Gaps remain on weeks with weather cancellations; we annotate those weeks rather than interpolating.
