Map up to six overnight arrangements across one trip and identify exactly which nights are uncovered or double-booked.
Why this is different from a simple hotel-date check
Real itineraries can include hotels, family or host stays, overnight trains, ferries and transit nights. This tool treats accommodation as a complete night-by-night travel story rather than assuming every night must be a hotel.
What to do with a gap
An uncovered night is not automatically wrong. It means the itinerary needs an explanation. Add the genuine arrangement—hotel, host, overnight journey or another stay—before relying on the accommodation evidence.
