According to the Mears calculator, from DTD (the closest point, I think), it would run you around $30 one way--and that's not taking into account I-4 traffic. I'm with Anne on this one, it is just a mall--a mall with cool fountains and some nice restaurants, but still just a mall.
Angela, $50-$60 is too high a rate just for the Premium Outlets, which are actually fairly close; maybe he thought you meant Millenia?
