Everthing can be done with not to much rushing when :
- start in Aswan fly direct to Aswan
- felucca and Minibus to Luxor
- fly to Sharm all activities based from here.
- fly to Cairo

I don't know, bro, it looks pretty exhausting to me. I'll be there the same time, so maybe I'll sit and a cafe and watch for you as you flash past like roadrunner! A couple thoughts:
- Speed is the enemy of budget travel. The faster you travel, the more it costs. You have no flex time, so you'll have to pay maximum prices for every cab and bus ride.
- You itinerary seems to me like this: run, run, run, felucca, run, run, run, run. I'd die on this schedule! But then again, I know people who enjoy travel like this.
- Flying from Cairo to Abu Simbel might save you a lot of time, and isn't that expensive.
Come ON. I don't see Dendara, any of the oasis towns, or Alexandria on there! Also, don't you want to check out the Suez Canal? and what about kicking back and just chilling in Dahab? maybe attend an all-night rave party or something?
Also, there's lots to see in Cairo. Don't you want to tour Islamic Cairo and then party with some hotties in Zamalek? Don't forget about picking up the good souvenirs at the Khan el-Khalil!
