Hi Suni:
The travelogues by our fellow ILites could be a good guide.
Check these out :
Egypt - The land of Pyramids My trip to Egypt last month.. Egypt, the land of pyramids, mummies and much more....!
Each one of these members starts their trip from a different country but none from the US (if that is where you would start your journey from). But I'm sure you will get an idea as what is a must to visit.
Have fun!
