it's been a while but the 2 cruises I took (4 and 7 day) were both excellent. we're doing the pyramids in early Dec--3 nights in Cairo and plan to book cruise and domestic air, Abu Simbel as second trip. THAT was worth every penny and the extra time! I loved Aswan spice market too!
Word of warning--check the dates for this fall--the locks at Esna are closed part of the time so the ships will stop and the trip will continue by bus to Aswan or and reverse... I have a recommendation for an agent in Cairo--American who moved there 1995ish. Would you like the info?
cruises are nearly all outside suites--some have pic windows--tours are early in the AM due to heat--Karnak Temple is right there--unbelievable sight! and going "up" the Nile to Aswan is such a joy. Life along the Nile is amazing too. Sailboats, fishing...
