Land Trip from Manila to Zamboanga City

Jessie, my cousin who has settled in Zamboanga City, has been inviting us to visit them. Last year, we planned of going there to visit him and his family then explore this wonderful place. But, it did not push through. This year, we are planning again to go there but by land instead of by air. In this way, we could also see other places and not just sky and clouds. We would take the shorter Mindoro, Panay (stop at Boracay), Negros route in going there and perhaps the longer Bicol, Samar, Leyte route in coming back. I just hope it would come true this time.
