Once you are in the parks, both Universal and Islands of Adventure together with City Walk are all right there together kind of like one huge park. City Walk is in the middle kind of seperating the 2. Also, I have never used it but I think there is a short cut from Universal to IOA as well, so you don't have to walk past City Walk, some of the vets may chime in on about that, maybe its just through the Hard Rock area? Not sure, but either way short walk.
