When the day changes, the plan changes with it.
ASUOU watches the signals that tend to break a trip - weather, closures, and delays - and offers a sensible alternative that fits the same time slot, before a spoiled stop turns into a spoiled day.
Three things most likely to derail a day.
Weather
A wet afternoon on an open-air stop is flagged early, and an indoor alternative is lined up nearby.
Closures
A site closed for the day or fully booked is swapped for something comparable in the same window.
Delays
A late arrival shifts the day forward so the rest of the plan still fits, rather than collapsing.
Same 1:00 slot, a drier plan.
Rain lands on the open-air food tour. ASUOU keeps the time, keeps the intent, and slots in a covered alternative close by.

An honest note on coverage
Adjustments are only as good as the signals behind them. Weather-driven reroutes rely on forecast data and are strongest for outdoor stops; closure and delay handling depend on the booking and transit sources connected to a trip. Coverage is broader in well-served destinations and lighter off the beaten track - ASUOU tells you when a stop sits outside what it can reliably watch, rather than pretending otherwise.
Build a plan that already knows what to do when it rains.
Reroutes are part of the plan from the start, not a scramble once you are already there.
