What lead you to be living there?
DHs job. Fantastic progression with a great salary.
Is it different to how you imagined, and if so, how?
I'm not sure what I imagined tbh! We read lots, researched, joined expat forums etc. But honestly, nothing could've prepared me properly. I wish I hadn't believed half of what I read - I was terrified of putting a foot wrong for so many months. I look back now and feel a bit foolish. As long as you don't go out drunk, eating a bacon sandwich and wearing a bikini, there's not much that can go wrong. Respecting (if not exactly agreeing with) the local rules and customs when out and about is key. You can always piss and moan about it to your fellow expats over a glass of homebrew red wine within the comfort and safety of your compound walls 
I’ve been fascinated with Saudi since I read ‘Princess’ aged 11. I’d love to be able to visit.
You should be able to soon! The Crown Prince has stated that regular tourist visas will be issued soon. For all the horror stories you hear, Saudis are very proud of their country and want other people to see how special it can be. I'd just advise before you come, get advice on where, what, when, how are from someone like me 😊
