Wow!! Interesting how a question one posts can totally diverge from the original poster's intent...
Perhaps I didn't make it clear that in posting I wasn't and AM NOT worried about safety issues in Egypt, as a woman or as a westerner--I've travelled alone in Mexico, Guatamala, Honduras, Belize, India and the US, all for extended periods of time. This doesn't mean I'm immune to danger but but it does mean I'm familiar with the ropes.
The reason I posted is I wanted to know where I'd find like-minded people to party with when I'm not diving!!! My only "fear" is getting stuck hanging out with couples!!! Or with people who don't share my general interests in independent, cheap travel, laid-back partying (no "kegger" type frat parties or massive techno parties!!!), different cultures, languages, music etc.
However: I'm very grateful to all of you who took the time to post, it's really interesting to read your thoughts and experiences.
CRISPOS--hi there from a fellow Torontonian!!!
So far from what everyone's said it sounds like Dahab tends to attract people like how I describe myself. But what about Marsa Alam? What types tend to go there in terms of average age, nationality, marital status, income etc?
