Daily density
Stops are compared with trip length, transfer time, traveler profile, and fixed commitments.
Trip Reality & Feasibility Checker
Stress-test an itinerary before booking. See the exact constraints that lower feasibility and the details that still need an official source.

How the checker evaluates a plan
Boundary days
Arrival and departure days receive less usable time than full sightseeing days.
Change friction
Hotel changes and self-transfers add packing, navigation, and missed-connection exposure.
Verification gaps
Unknown entry rules and airport transfers become explicit actions rather than hidden assumptions.
How itinerary changes affect pressure
| Change | Rule effect | Planning consequence |
|---|---|---|
| Remove one hotel move | Removes a 4-point deduction | Less packing, checkout, luggage storage, and orientation work |
| Add an open half-day | Avoids the 12-point no-buffer deduction | Creates room for weather, queues, fatigue, or a missed priority |
| Protect a late arrival | Acknowledges the 8-point boundary-day deduction | Stops arrival evening from being counted as a full sightseeing block |
| Replace a self-transfer | Avoids an 18-point tight-connection deduction | Reduces missed-segment exposure when separate tickets are involved |
The score begins at 100 and applies only triggered rules. It is a comparison aid: a lower score identifies where to simplify, not whether a trip is safe or bookable.
A six-day family plan with compressed boundary days
Illustrative rule application using the published dataset.
Inputs
One Seoul base, family profile, four stops per full day, 19:30 arrival, early departure, 70-minute typical cross-city transfer, fixed tickets, and no open block.
Why the score falls
- Long transfers: -12
- Late arrival: -8
- Early departure: -8
- Multiple fixed tickets: -8
- No open buffer: -12
100 - 48 = 52, before any destination-friction adjustment.
Revision
Group stops by district, remove one fixed booking, and keep one half-day open. The route stays recognizably the same while the plan gains recovery space.
Edge and limitation
A mobility need, heat warning, major event, closure, or unusually long queue can make even a high-scoring plan unrealistic. The checker does not read live conditions or personal health constraints.
Recalculate the revised route cost and verify current transport and attraction operations before payment.
What makes a travel plan infeasible?
Too much movement
Many stops and hotel moves add packing, checkout, luggage handling and navigation. Count the full door-to-door transfer, not only the scheduled train or flight.
Compressed arrival and departure days
A late arrival does not provide a full sightseeing day. A morning departure can remove the previous evening’s flexibility too. Leave room for check-in, food and recovery.
Pace without buffer
Families, mobility constraints and fixed reservations change what a day can absorb. Protect breaks, accessible routes and slack between commitments before adding optional stops.
The score is a planning heuristic, not a prediction of whether your trip will succeed. Review each triggered deduction and adjust one constraint at a time. A higher score cannot verify transport availability, accessibility, entry permission or booking terms.
