A destination can look close on a map while requiring several transport steps. Distance alone does not show waiting time, road conditions, boat departures, or the difficulty of finding a return ride.
Count every connection in both directions. The return journey matters as much as the way there.
Keep Dumaguete stops together, use a separate inland day for Valencia, and give marine or island trips their own protected time.
Choose a simple weather backup such as a city food route, museum, café circuit, or relaxed Boulevard afternoon.
