Luxor was built on the site of the ancient city of Thebes, and the magnificent monumental architecture and its excellent condition make Luxor one of Egypt's greatest tourist destinations. For many hundreds of years people have been visiting the temples of Luxor, Karnak, Hetsgepsut and Ramses II. The Nile has feluccas and old barges that shuffle between the luxury hotel ships of the Hilton and Sheraton that cruise between Cairo and Aswan. This area is suited for Egyptologists and those interested in ancient history, monuments and cultures, Luxor is a "must". It is also a winter resort with genuine sunbathing weather, the wondrous temples and tombs an added bonus. The extremely hot summer months constitute low season. The accommodation here consists of hotels outside the centre which are quieter with more relaxing settings, those nearer the centre are more convenient for sightseeing without transport. Standards are not as high as elsewhere, so a 4-star is probably the lowest category acceptable to most tourists. 3-star hotels used by tour operators will usually provide clean, very simple accommodation with little charm and few facilities. The majority of hotels have security guards and electronic alarm gates at the entrance.
