I think it is worth it. Like others have said, if you plan on eating and one of those three places look good to you...do it.
I am glad I did last year when I went in August.
We didn't have to wait in a long line and once we were done eating, we headed to the arena's back gate...sat down in our section immediately and had to only wait 20 minutes for the show to start while others had to stand outside the arena atleast an hour before hand. It left us feeling like real VIPs
