Resort revenue managers in Jeju often watch total occupancy first. That single line hides the more useful story: which booking channels are bringing guests from which prefectures and provinces, and whether those guests stay one night or four.
We map OTA-sourced reservations against direct bookings by origin prefecture. When domestic weekend share drops while Fukuoka and Shanghai corridors grow, the weekday gap chart usually widens before ADR softens. Catching that widening early gives housekeeping and F&B a clearer staffing picture.
A practical step: pull twelve weeks of channel-tagged reservations and plot length-of-stay by origin band. If the median shifts from 1.8 to 2.6 nights for one corridor, your laundry and minibar forecasts need updating before the next holiday block.
Properties that share anonymized extracts with us receive annotated versions of these charts in the monthly review cycle. The annotations call out dates tied to local festivals or flight schedule changes so the numbers stay grounded in calendar reality.
