Hi Mushtaq.We found the Tour Co. in ' Hurriyet Newspaper '. Every Monday they have a travel Section.We used Hey Travel Trends of Istanbul. ( sorry no web address ) They use Sonesta Cruises and are only 5 *. Excellent Boats and first class service.We sailed on The Sonesta Sun Goddess.Our hotel in Cairo was the Intercontinental City Stars. 5* De-luxe and it was.It also next door to Egypt's largest shopping centre which is connected to the Hotel.Mrs M would love it but take your Cards !!!! The Hotel is 10 minutes from the Airport.We had 3 nights there and 4 nights on the Boat and 1 night back in Cairo at The Meridian also 10 minutes from the Airport.following are two other Turkish Co's which do the same or similar tours.
