Regarding VIP seating...if I remember correctly, haven't a large number of prime regular, bottom (not floor) center section seats been set aside for them each year in addition to the boxes described by Libby? I seem to remember wondering why my team (and others competing on Einstein) were stuffed in sections to the side of center and seeing many empty seats available and teams getting over to Einstein later than other ones eventually being placed in the prime section
There were empty seats last 2 years in that section even after moving in late comers. Not really complaining though as we were happy to be closer to the floor than other teams not on Einstein
As far as setting up stands in convention center...it is doable for Divisions (as we have seen in St.Louis) but likely extremely expensive to set up an Einstein arena with 25-30,000 additional seats. We got quotes for $40-60,000 just for 2000 seats at a convention center here in Las Vegas for our regional. Can't imagine the cost (and time) associated with setting up temporary seating for 30,000 just for Einstein.
