Hurghada has come on quite a lot recently. We now have a very chic Marina with lots of nice places to eat and drink. Papa's Bar is now located there. Not far away are Hekandi and Ministry of Sound.
Sorry I have to disagree with you about the rain, last October we had 7 drops - yes I tried to count them. I was the idiot standing outside, arms thrown apart shouting 'yes, yes, yes'. By the time I had finished my third yes, it was over!
There are bars and discos here. In Sekalla at the La Pasha Resort, they have their own disco. Up in the touristic area, there is Hard Rock, The Dutch Bar, and opposite the Sultan Beach there is a lovely bar/eatery with good prices i.e. don't rip off the tourists.
Weather in October can be quite humid but it is still warm enough to swim in the sea, in fact until the middle of November is very pleasant but not too hot.
Come and enjoy.
