I’ve rented a few times in Dubai and the experience really depends on the company. Last time I went with SOS Rent Cars and it was smooth – decent selection of cars (from Mercedes to Lambo), they deliver to the airport or hotel, and no crazy hidden fees. Here’s their site if you want to check: Booked a Porsche 911 for a few days and everything was exactly as agreed. Just make sure to reserve early, especially if you’re coming during high season. Definitely beats the usual rental companies.
