I am undecided as to whether this would be helpful/desirable or not but, just to add it to the mix, some people have said that if you get an 8am ressie at Hollywood and Vine, you can beat some of the crowd to jedi sign-ups and then make it to TSM before lines get crazy. Of course, the tradeoff is that you would have to really rush your expensive character breakfast since the park seems to open between 8:35am and 8:45am from what I understand.
