It's super modern and kinda surreal. For a first-timer, I'd say a solid 4-5 days lets you hit the highlights without feeling rushed. You can see the big landmarks, do a desert safari, and still have some downtime. Longer is great if you want to explore beyond the main tourist areas, but a short trip is definitely enough to get a taste.
