I should elaborate on my answer a bit, Dubai's attractions are spread out, for instance the Hyatt Regency might make a good base if you wish to do some cultural exploration at the old town or souks, but its a good way from the Mall for instance. There are no jogging maps or walking maps because no one walks if your a tourist ( the palms at dusk was full of expats exercising). I am not sure what the price of taxis are like, Dubai does have a very good rail system that I regret not exploring on this trip, but even that requires some walking to attractions and is mostly for the residents AFAIK.
