I've been to the Philippines many times, lovely country nice people. Mindoro is a nice island and the scuba diving at Puerto Galera is excellent. As for bikes I always rent myself and ride where I like. But I am fairly independent.
Don't expect excellent food as it is not like any other SEA country (catholics and america had a fair crack at the place)
When you get to St Jose ask about Pandan Island...
Go for it...
