Good advice from f3nikon, I would add, take many shots of your subject when you can. I found the Autofocus to be rather hard to control. It does not always focus on what you want in focus and the display is too small to see whether it is crisp or not. So, take several shots regardless of how nice it looks in the display after you took the shot.
Also, bracket your shots. Try different shutter speeds and different f-stops ont he same subject. This will give you a greater choice of shots when you are processing and help you learn what parameters work better for different types of shots.
I can't count the times I got back with what I thought was going to be a great shot to see that it was out of focus or overexposed, etc.... Had I taken a few more shots with different settings, I would have probably gotten a better shot.
Have a great trip!!
