Whilst all well and good, none of that stuff is really specific to Egypt, I’d say.
Re tripods – you have to be specifically going out to do photos, really. If you are on a sight seeing trip your family/companions will soon get pissed off with you stopping to fanny about with a tripod for ten minutes all the time. And it’s not like you’ll be short of light, unless you want to do your fannying about in a pyramid.
The fast primes are best for when you are hanging out with a bunch of people, you will get great portraits. Otherwise, if you are out in wide open spaces, they are of limited use. I have one, it gets used for people.
A wide angle would be most useful I suppose. But all those things you mention would be (and are, in fact) part of a general setup.
On the subject of fisheyes – at first you take a few photos and think ‘oh’. But it takes a good bit of thought to begin to understand what it can do for you. You don’t just take pictures ‘of’ stuff, you use the lens to paint cool pictures with the stuff around you.
