Our holiday to Egypt this week (Nile cruise + 3 days in Cairo) was cancelled. Assuming that the situation there returns to normal in the next few months, we will probably re-book for November 2011 or February 2012. Is one of those periods preferable to the other?
Just check the date of eid ul-adha and also Islamic new year - I think these will be in November. They are only a day or so each butmight affect opening of sites, shops etc.
I went in November last year on that itinerary, and had a really good time. Weather very pleasant, and sights were fabulous. Hope the situation settles down soon.
