This "tour" is not worth 1/15th the cost of the ticket.
The local information piped in through headphones is basic and poorly timed, adding no real value. The size of Dubai is not conducive to this type of tour, as you spend most of your time on the bus.
Save your money and hire a taxi for a day or 1/2 day rate. You can grab a brochure of the bus trip and hit the spots on your own.
