To hire a guide or not to hire?

[Joseph Smith]

At first, I thought it worth hiring a guide for a whole day. Nevertheless, I realized that I can find all information about the country I want to go to in guidebooks or Internet, you see, there is as good fish in the sea as ever came out of it. Now I think on the dilemma whether it is worth paying for a guide. Let's say I travel to Damascus, I think it's worth taking a personal guide, because there is nothing to speak about the city. But as for Istanbul, there is a good deal of information on such a site as private guide site. I do not see any problems. So, I think, especially if you have a habit of using the guide services, and you want to learn more than the usual standard information from any sources, so maybe you should consider the possibility of using such a professional service. What do you think about that?
