Great report as always @drrich2Trailboss123's land-based Philippines trip sounded good; I don't know what it cost, all expenses included.
For my Philippines trip, airfare was $750 round trip from Seattle- likely a bit more for you. LAX and SFO seem to be the best gateways to Manila from the USA.
I paid $1614 per person, double occupancy, for 11 nights accommodation and 10 days of diving at El Galleon/Asia Divers. Diving was 4 dives per day. Optional night dives were additional. We did 2 trips out to Verde Island, which were also additional- but nominally so - I want to say $35 for each 2 tank trip. $1614 price tag included a buffet/all you can eat breakfast, as well as grand transport from Manila Airport to El Galleon round trip. We did lunch and dinner a la carte which averaged out to about $7.50 per meal, but mostly ate vegetarian, but not exclusively. We certainly didn't skimp and portions were abundant. Nitrox was also additional- I believe $125 for the 10 days, but upgrading to 100 cubic foot tanks was free. So, all in, call it $2500 per person for airfare, ground transport and diving with Nitrox and accommodations and breakfast. Another $150 to $200 total for lunch and dinner, per person. There are always incidentals which will be variable for each person, such as alcohol, airport parking, tips, etc - Again, this was 11 nights and 10 days of diving. Pretty reasonable as far as dive vacations go.
