Cairo stopover programme on Egypt Air?
From my experience in May, I did not have to contact MS in anyway, I just followed the signs to the stopover desk and they already had my name on a list. They took our passports and then gave us some paperwork and we waited for the desk people to finish the immigration paperwork and whatever else. We were also approached by Karnak if we wanted to take a tour also. The tour costs money the room does not. They then call you and whomever else is going to the same hotel with you and escort you to the hotel shuttle bus. At the hotel you give them your MS voucher and they give you the room and meal vouchers and then do whatever you want until your shuttle leaves 2 hours before your flight back to CAI. I am not sure there is much more to know that this post or the one the one that I posted on here a couple months ago.
