re safety in places like Jordan, last year I was all over Egypt. The hotels had scanners too, as did the major tourist sites. Security was very tight at places like the Valley of the Kings where a major terrorist episode happened a few years back. I never felt unsafe at all though.
Whenever we were travelling from place to place i.e. Aswan to Luxor, we had to go in an armed convoy. It was certainly different! Some in our group were very upset, but I was delighted as the Egyptian government were obviously looking out for us. Like Jordan, tourism is very important to Egypt, and they are taking serious steps to keep the country safe.
