I am planning a trip from Dubai to Abu Dhabi and I am looking for some advice on the best way to get there. I am wondering if anyone has any tips or recommendations on the best way to travel between the two cities. I am looking for the most cost-effective, convenient, and safe way to travel. I am also interested in knowing about the different transportation options available, such as buses, trains, taxis, and car rentals. Any advice would be greatly appreciated. Thank you!
