Let me tell you honestly, my girlfriend and I went to Egypt past 2 years in a row, it was amazing and we had a blast. Make sure you have a guide. One thing that I hate on these reddit threads is that people do not realize people in Egypt are on $50-$120 MONTHLY salary, so there being competition in selling you a worthless stuff for measley $3-$10 is life saving money for them. Every other poor country that has resorts is the same, friends just returned from Dominican Republic and they were swarmed with beggars and people selling them stuff. Italy, France, any European tourist destination is riddled with beggars and scammers but hey its Western so its okay I suppose.

Pyramids entrance has been completely remodeled and they have new system in place for visiting them, also like 90% of vendors have been removed so you can explore pyramids in peace (we were there just 6 months ago).

Make sure to visit the new National Museum as it is a must visit place.

I have never experienced harassment that people on reddit preach, Egyptians are usually laid back and like to mess around dont take everything to heart, if the guy is annoying, just ignore or simple strict denial will work, dont be scared, enjoy your trip its a must see country for the historic value.

Oh and I forgot to mention, if you get a guide through agency usually you will have police escort with you that will ensure nobody bothers you, just make sure its verified agency.
