The 4-day Lake Nasser cruise leaves from Aswan and starts with Abu Simbel; the 5-day one boards in Aswan and reaches Abu Simbel on the fourth day, with a dinner show. It is not the Nile cruise.
Included 3 nights' full board accommodation on the cruise ship on Lake Nasser. All entrance fees, excursions, and guided tours as described in the itinerary. English-speaking guide on tours. Port taxes.

With 4 days you see Abu Simbel straight away, then Qasr Ibrim, Amada, Derr, Wadi el-Sebua and Kalabsha. With 5 days you start with the dam and Kalabsha and finish at Abu Simbel with the evening of light and music, then return by coach to Aswan.
No. You sail on Lake Nasser, south of the Aswan dam; the Nile cruise between Luxor and Aswan has its own page.
Not many yet, especially for the 5-day option. Read the itinerary carefully.
