But bear in mind if you want rail and go right in front of the main stage, you probably won't be able to see anything going on in the middle with the screens, or on the smaller stage at the opposite end.
I thought that was the most brilliant part of the stage design on I+E. Rewarded people who did not show up days before to get to the rail. It was great to walk around and get different vantage points on the floor during the show.
Might have been the best setup I have ever seen, or at least experienced myself.
