@Gary Yogurt You are allowed you walk around and might be able to have some success on Friday in other General Admission areas. As far as getting into other grandstands, I’ve never had any luck doing this, especially during the F1 sessions. The number of ushers who inspect your ticket particularly on Saturday is unreal. If you have a grandstand 22 ticket that is where each employee is going to steer you and many will flat out refuse you access to some areas if you do not have the right ticket (like crossing the bridges to stands 1/2 or 11/12). I think to get to my seat in grandstand 11 last year I was stopped a dozen or more times to have my ticket inspected.
