Maybe, but WF can flip the arena overnight and probably has no requirement for a shoot around for their professional teams, so those 60 dates stay at 60. After flipping, they probably have staff still fresh to do an 8 am concert load in. I doubt if Hilton has the staff capability to pull that fast turnaround and still be able to meet the staff requirements for a concert, thus Hilton would require more schedule time to make an event happen, like maybe 2-3 days, cutting into schedule flexibility. Global Spectrum obviously has some schedule influence as they make their pro teams take extended road trips at HS tournament time, that would not work with BIG12 scheduling.I mean this sincerely there are like 60 games between basketball and hockey that are played there every year, It can't be a whole lot different than Hilton when it comes to that schedule flexibility.
Also Global Spectrum can commit to a tour, and if they cannot clear the date; they can move the act to one of their other venues, an option Hilton does not have, unless they are dealing with a promoter that has other venues that he can call, but I doubt if Hilton has that option.
There are other variables, but WF is not maintaining its success on seating capacity, in fact; I am pretty sure they can cut seating capacity with curtaining of the arena, as they do for many shows.
