Not all types of camera batteries are on sale. Therefore be sure to have batteries that will last the entire holiday. People do not always like being photographed. When in doubt it is better to ask first. Sometimes they will say no. Every now and then they will ask for money. When visiting official tourist sites with a video camera, be prepared to pay high additional fees for using your camera. For taking photographs an extra ticket is also often required, but this is considerably cheaper than it is for a video camera. At a number of sites you are not allowed to take a camera; you must hand it in at a special reception desk. Using flashlight is always prohibited.
