Could have a bit more information on the headset audio guides. Nice for the first day to get an idea of the city.
I paid in pounds however, and am pretty sure I got ripped out with my change in Dhirams (I paid 25£ for two people for one day, and on our receipt it was 145 dhirams!! I also paid 40£ and recieved 150 Dihiram change, so I effectively paid 30£ in total for two of us!)
I would recommend going, but pay in Dhirams, and make sure you don't overpay. But a good way to have a look around the city and hop on and off
