so in august after i visit israel i will be flying to egypt for 11 or so days. i would like to get any advice about the absolute musts that i will need to cover in that time and the probable costs and any other tips or advice. i was thinking cairo-aswan-abu simbel-luxor
I spent around 11 days, in Egypt, too.
But I cant help u much. I spent most of the 11 days, at an oasis town, in the desert, around a 4 hour train ride from Cairo. Maybe, u would like a couple of days, in the desert? I forget the name of the oasis town, but how many of them can there be, within a few hours train ride, from Cairo.
I did Aswan-Abu Simbel-Luxor-Cairo in 3 weeks and still did not get to see everything I had wanted. You'll be very rushed and need to plan carefully.
I recommend the following:
Book in advance a connecting flight with Egypt Air from Cairo to Aswan on the day of your arrival in Cairo. This wíll save you time - first the time getting to Aswan and second the double transfer into Cairo.
On the very first day in Aswan book your trip to Abu Simbel for the next day and for the day after that, arrange a felucca trip for two days, one night down the river and with onward connection to Luxor. If you are not too tired, try to visit the Nubian museum in the evening of your first day. (Feel free to skip the felucca trip and to add the sailing day to your days in Aswan.)
On the fourth (or fifth) day you'll arrive in Luxor. Take about 4 days to see the things there. In Luxor, book the luxury night train to Cairo immediately on arrival. You'll be in Cairo at 5 a.m. - just in time to drop off your bag at a hostel and then rush to the Pyramids before the heat sets in. Get back for lunch and explore Khan El-Khalili. Then you'll have just one day left of your trip - use it to see the Egyptian National Museum. Next day: fly home. Very rushed, but do-able with careful planning and lots of booking ahead.
Hope I helped a bit.
