Your best bet is to go to the bookstore and browse their travel section. I don't know where you're going, but it's best to browse that section. You should just take your camera, know your camera, and shoot everything. It's kind of a nice way to really survey what worked and what didn't. The first time I ever traveled with my camera I shot over 20 rolls of film. I shot EVERYTHING! I came home after three days and checked out all of my photos and discovered that there were some really great ones in there. I ended up going back about 4 months later and reshooting some of the spots that I shot previously.
No one can really tell you what to be on the lookout for, especially since you weren't very open with your location.
