Shop around for any trips as they will be alot cheaper than with the reps in your hotel.

You can easily arrange a trip to Cairo or Luxor quite cheaply yourselves via Egyptair - pick Egypt as the country as you go into the site as you will get cheaper prices. The earlier you book the cheaper the prices tend to be also.
You can then book a guide yourself with driver. We done this last year and flights were £30 each return and guide and driver £10 each for the whole day.
Just print off your e - ticket and take to check in.
