Hi Stewart,
Watch out with the money.
IMHO, don't go overboard with the money you give her.
If she is from the province she will have a different set of values than the city girls.
Get to know her first before commiting yourself to any regular financial commitment.
Keep all flight e-tickets and boarding passes.
Keep your hotel receipts, and take photos and put trip 1 etc.
Keep a diary of your adventure.
Hopefully it will be a pleasant and rewarding one.
Best of luck and enjoy the lovely ways a Filipina can make you feel
