Alleenstaande ouder met kind (ongeveer 9-11 jaar) gezocht

We have booked flights to Egypt for the autumn holidays (RLP), and wanted to see the pyramids during the 2 weeks (approx. 2 days Cairo) and spend the rest as a beach holiday in Hurghada and/or Marsa Alam. Preferably with snorkeling/diving in the house lagoon. Happy to have some action in any area. In principle, quite open to everything. As a solo traveler with a child, you usually only meet families or couples with children, which is perfectly fine in principle, but why not specifically look for someone in a similar situation. My son is 10 years old and in the 5th grade of Gymnasium.
