Went in october this year to sharm, 37 - 40 deg everyday, great weather and the sea was fantastic, swimming with the marine fish is something i will never forget but then again neither is the food, i stayed away from anything i would class as suspect and still got ill and lost 3 or 4 days of my holiday with gastroenteritous (spelling) bad stomach. We were all ill at some point and not even right for about 2 weeks after returning.
We stayed at the sunrise island view in sharm 5 star, right on the beech, the brochures look great, all inclusive, pool bar, beach bar etc, reality is that its a muslim country and the all inclusive beer is like soap water and the cocktails were un-drinkable, we ended going into sharm to the hardrock cafe which was great.
Food wise we felt they catered for the russians and germans etc so the food choice was limited and boring after 2 weeks, and can i add from expirience the russians are the most arrogant arseholes ive ever met.
The excursions are expensive and sharm is a long way from cairo, different continents even, asia and africa, the flights to either the valley of the kings or cairo were £600 for 4 of us or you could go by bus which would take you 6 hours and cost £175, then 6 hours back.
Would i go back, no, it cost me in total nearly 4k and i have enjoyed mainland spain more in the past and at least you can eat without worrying.
This was only my expirience and and you may well enjoy it but i went there and thought i would be amazed but found it to be very basic compared to some of the other places ive been.
