The other tourists always tell you how breathtaking the view is when you stand at the top of the dune crest at sunrise and look at the landscape 300m below... bullshit. You look into a glistening bright star, you can't take pictures against the sun anyway and you have to wait until the heart attack is over. And you can't get any good photos from up there, I know that because I've been up there. With tripod and 20kg photo luggage.
