Photography should always go with travels. If you couldn't keep pictures of your travels, it seems like you haven't traveled at all. The way pictures are shot matters a lot. Great shot are the ones worth keeping.
As a traveler, I sometimes get an opportunity to go with travel buddies whom I consider great photographers. There are elements that make good pictures like composition and exposure. And the subject (hehehe).
I proudly give credits to my friends who shot most of my favorite pictures. Here are my top most liked travel photos (in no particular order):
Caroline Espejon, Pen Casel, Tina Corpuz, Arthur Yap, Olan Emboscado, Keir Ashley Lim and Joems Escovilla
