Yes. There is a sidewalk the entire route. If you switch to Earth view on Google Maps or Bird's Eye on Bing Maps, you can see the sidewalk. The biggest issue is crossing Kirkman Rd, which is the main north/south road that sits between the hotel and Universal property. But, there's a crosswalk and "walk" signal so it's not really an issue.
I used to live right down the street, about two minutes past the DoubleTree off of Kirkman Rd. I used to see people crossing the road all the time. It won't be a problem.
