Istanbul is considered a mega city, which means that it’s a epicenter for trade, in terms of economics, in terms of finance and business, in terms of culture and entertainment; and with Turkey’s relatively recent admission to the European Union, you really have a situation that’s perfect for tourism. Visas and such are easy to get from various countries, especially the States and when you get there, while you’re on these Istanbul tours, you’re just sort awestruck because of the unbelievable mix of ancient cultures and yet high sophistication about its world architecture. It’s like being in the past and the future at the same time. You see the vestiges of the Ottoman empire alongside modern and post modern building; modern art building, super high end hotels and resorts; skyscrapers, and yet the most culturally important, and historically significant monuments, palaces, and other very interesting sites and areas to visit, such as the Golden Horn.
