The only thing I would change is that the first day - coming right after most people had taken trans-oceanic flights and still had jet lag - was too demanding (flying to Luxor, touring Karnak before checking into ship). It would have been better to have a lighter Day One to allow for rest and time zone adjustment, and do Karnak on the way back.
The all-women's tour group and the Tour Director were outstanding and hugely enhanced the experience.
Tipping became a constant irritant and would be better if Tour Director handled tips and Insight appropriately raised the package cost, to alleviate that daily chore (ensuring correct currency & denominations, ATM visits, etc.). PS - bring American dollars in small bills.
Overall, a fascinating country, knowledgeable and constantly helpful Tour Director, and a good balance of historic and current experiences. Aswan (and the Cataract Hotel) was a definite highlight, and don't pass on Abu Simbel. It is worth the cost; as is the Aswan boat tour of the Nile (two options worth doing).
