Can somebody tell me what kind of weather it will be in mid Dec. Will it be too cold (mean less than 15-20 degree Centigrade) as I have small kids with me who are not exposed to low temp.

Is Mid Dec. a peak season for Cairo (for tourists)

Further are there good serviced apartments (with kitchen, utensils etc.) for a short stay of 4-5 days. Kindly provide me contact details of the same. In what budget range will these be available during Dec.

Any guidance highlighy appreciated.

Firstly tell me where you want to visit then I am able to tell you weather of that place because you didn’t mentioned any particular place.

It's very cold especially at night. In the sun, it was maybe 15C?
We spent a few nights in the desert and I thought I was going to freeze to death! I had a couple of layers of clothing plus 8 think blankets and it was still cold. It was super windy, probably around 0C.
Marrakech was the 'warmest' city we visited.

hope u have great fun at the place..
thanks...
