Hi,
I am from Philippines and stays there for about half of the year =) if not travelling for work.
Try to visit Subic next time on a side trip from Manila. Stay at one of the Marina Bay villas for a cheap $100/nyt. Google it and you'll see a bnew villa available for $100. It is also located near the beach with lots of bars to choose (Pier One, Cascades, Cork Room, etc) for fun and music. And the crowds mostly local. Eat local delicacy at Gerrys Grill while relaxing in the beach ( no swimming allowed though near the bars and restos).Proper beaches are about 10 minutes drive away.
It is one of the safest place in Philippines I would say even at night time.
While you are there you can try exploring Mount Pinatubo ( volcano) and go to Grande Island.
It is just a 2 hour drive from Manila. I am from Subic and would gladly give inside info on where to go or stay in Luzon part of the Philippines ( Manila/Subic/Baguio).
