I worked out I spent £2500 total including return flights for 1 for 20 days in Phils (maximum is 21 before needing visa). Mainly 4* with 1 night in the 5* Manila Hotel balanced by a 3* resort, average 2500 peso per night. 4 local flights for 2 of us, a few gifts, plenty of taxis. Food we budgeted 100 peso (£1.50) each for lunch and 500 each for dinner and beer.
You could get basic aircon room with hot shower for half that, if you could find an apartment that could be cheaper again and you could save money on food with the added fun of using local markets if you cooked yourself. Also easier to live cheaply away from the main centres.
