Just spoke to Mr Gaddis, the Honorary British Consul in Luxor. He confirmed that there is no curfew in Luxor and has never been and that he has recommended to the Vice Consul this morning, that the travel advice for Luxor be down graded.
The sites are open, feluccas are sailing, balloons are flying, guides are guiding and drivers driving. Several digs are operating but most have gone home.
Obviously there are still political issues but these are not affecting foreigners.
