Excellent source tells me that is not the case. Grandstand Seats won't be in yet and bolts will be exposed. Goal is to allow ALL fans to try the grandstand on a GA basis for 2 weekends... then re-seating will occur.
Also need to complete all other premium areas (suites) in order to assign Grandstand seats...
All tickets this year start off as general admission... You just pay the excellence fund fee based on where your renewals will occur. I guess if you are bleacher and want to move into GS, then you would pay the upgraded Excellence Fund fee once you actually get to claim those GS seats.
