Have a safe travel! If you are staying mainly in Manila,there are lots of Historical places such as Intramuros, fort Santiago, rizal park,etc. There are also museums in Manila like National museum of the Philippines, Ayala museum, Mind museum,etc. if you want to go shopping, go to our Mall of Asia. I think it's the third largest mall in Asia.visit also bonifacio global city. I heard the place was nice although I haven't personally see it. If you want to see beaches, you have to go outside of Manila. You can go to Northern Luzon to see some more beautiful sceneries like Baguio city, Banaue Rice terraces and some beaches. If you want to go further he next island after Luzon is Visayas. Take extra care while you're traveling. We are very accommodating but careful with people who take advantage. It's like in every country, there are different kinds of people.
