What does the ninth day actually buy you?+
A second full Cairo day at the end, on day 8. That is the Royal Mummies Hall at the National Museum of Egyptian Civilization, the Citadel of Saladin with the Mohamed Ali mosque, and Coptic Cairo with the Hanging Church and the Ben Ezra Synagogue. On the eight-day version that day does not exist and you fly home instead.
Is the Nile cruise private or a group?+
It is split, and the operator is clear about it. Both Cairo days are private tours with your own guide and driver. The sightseeing from the boat is shared with the rest of the cruise group. If you want the temples along the river to yourself as well, that is a different trip at a different price.
Are domestic flights included?+
Yes. Cairo to Luxor on day 3 and Aswan back to Cairo on day 7 are both inside the price, along with every airport transfer. International flights into and out of Egypt are not.
Can we add Abu Simbel?+
The operator offers it as an optional tour on day 7, the morning you leave the boat, and it is not in the price. It means a very early start from Aswan rather than a whole spare day. Say so when you send your request, so the flight back to Cairo is not booked over it.
How much walking is there?+
More than most people expect, though none of it is difficult. Giza, Karnak and the Valley of the Kings are long walks over uneven ground with very little shade, and a tomb usually means a ramp down and back up. There is no climbing or scrambling, which is why this is graded easy, but the Cairo day on day 8 is another several hours on your feet.
What is not included?+
International flights, your Egypt visa, extra meals and drinks, optional tours including Abu Simbel, tipping, and additional entry tickets. That last one catches people out: going inside one of the pyramids, or into the tomb of Tutankhamun, is a separate ticket bought at the gate.
How much should we budget for tipping?+
Tipping is excluded from the price and it is a real line in an Egypt budget rather than loose change. Reckon on US$10–15 per person per day for your guide and about US$5 for the driver, plus US$5–10 per person for each night on the boat, which goes into the communal crew box at the end. Carry small notes; getting change is a daily chore otherwise.
