Also, Universal does not offer "line passes". I think the biggest issue is getting out of a line and getting back in if you have to use the restroom. In that case I'd speak with the closest CM and see if they can get you back in the line more quickly when you return. As was mentioned, there is no "front of the line" unless you are a child on a wish trip, and then it's only for the duration of that trip. Even they often have to wait.
