SWW: kids only want to do rides

So we will be at HS during SWW. The kids are not interested in any autographs or shows. They do want to see the opening storm troopers, though. How bad are the lines for rides if we arrive at RD?

pretty much just a little bump. Have you checked the wait time predictions on the Touring Plans website for your specific days? That will give you a better idea.
