Well Briar,
I personally like the idea of the lovely beaches, the very hot weather, plus I have always wanted to go diving, and Sharm seems the ideal place!!
The things that draw me and especially my girlfriend away from Sharm is that it is a tourist populated area, my girlfriend is put off by the recent tragic bombings, this doesn't bother me at all, but this could be a major no for her!!
Tunisia seems to have more culture (which is what we like), however the 'turn off' so to speak, of this area is the story's off peope getting hassled to an extreme, I know you can just say no, but me and my grilfriend aren't very good at dealing with hassle
I don't know why holidays have to be so hard
