I live in Vietnam, and my wife and I are visiting the Philippines with a couple of friends from mid-to-late January. We'll be there for about 15 full days, and we're looking for some "can't miss" type of things to see and places to go.
We don't want to overload ourselves with too much, but we want to see as much of the country and as diverse of areas as possible. Also, we fly in and out of Manila, so we'll probably either start with a day or two there, or end with a day or two there.
So, my question is, if you were only spending 15 days in the Philippines, where would you definitely check out?
Thanks so much for the help! Hopefully I can help you all someday if you make it over to Vietnam!
