Other than in Thailand, for the Philippines you better book accomodation and transportation in advance, to not get your luggane pulled away from you by some moronic taxidriver who insists 'bringing you to his sister's hotel'.
And many hotels in the Philippines are filthy abandoned garbage. (living) Standards are VERY different from Thailand.
Tip: bring some survival food like muesli bars etc. for te first days. Edible food can be far away, unless you don't mind eating the intestines of a cat.
