我不用Wechat therefore that info is useless to me

But I have read in both Chinese and English sites, that Egypt is a country you definitely would be better off to have a guide, unless you are very familiar of the country, i.e. been there several times, and have friends / family there...

A very usefulness of the guide is he can take care of countless 騷擾 from street vendors or anyone tries to get a few Le from you by offering this and that...  Even crossing the extremely busy street in Cairo, the guide can make the crossing much safer.  I am not kidding.
