Originally posted by baro-nite Haven't been to any of those places, so this is general advice.
Bear in mind the adage from Minor White:
That, in a nutshell, is how you avoid what you aptly describe as "look at this [thing]" shots. Look for shapes, patterns, contrasts, juxtapositions. Zoom in, look for details. Look at photos you like, your own work and other's, and think about why you like it. Assign yourself a project: a particular subject (something non-obvious), pattern, shape, or technique, and work on that for a while. Don't always be photographing: spend non-camera time with the group; devote other times to photography (especially early mornings and evenings when the light tends to be more interesting).
Above all, enjoy the trip!
welcome to the forum and congrats on the upcoming marriage

consider either a back up DSLR or a good point and shoot, just in case
back up your data, if you have a battery grip, bring the AA tray along with extra batteries and memory cards
