Go and see the sand for yourself, then relax in a desert resort.
Seeing as you're in the Middle East, it'd be rude not to see some sand not connected to a beach resort. Although Dubai may seem like a maze of highways, once you head out away from the coast you're soon surrounded by sand dunes, with the odd camel scattered here and there. It's fine just to have a drive around for while as the roads are all well-maintained, but if you've got time I recommend finishing things off with a trip to Jumeirah Bab Al Shams Desert Resort & Spa, a rather spectacular Arabian-themed resort in the middle of nowhere about 40 minutes from Dubai and a great place to unwind one afternoon to watch the sun go down. Relax with a drink in the rooftop bar, it's all quite magically and the perfect antidote the fast-pace of Dubai. And if you simply can't drag yourself away, the rooms aren't too expensive either.
