Some hundreds won't get you that far even if you will be staying with your girlfriend. That amount won't last for a month, expect to be going a lot of times with her family and you if you chose to extend your visa in the Philippines it would cost you about Php3,030 + transportation and meal allowance going to the immigration etc. At least have something like 1000 pounds because you're staying for a month and save some more if you want to get married here
