I don't know if I've ever really bought that line of thinking...though I guess I could see it more for concerts (where people regularly go to brokers to pay an arm and a leg for tix). They do this on Broadway a lot now: Premium seats. They set aside anywhere from 5 rows to upwards of the entire center section of the orchestra and block them off at $250 a pop. While major sellouts like The Producers (when Nathan Lane/Matthew Broderick were there) or Spamalot argue that it's a deterrent from scalping, it really just seems like an excuse to jack up already ridiculously high ticket prices. This is especially annoying for Broadway shows, because any of the unsold Premium Tickets can just be turned around and sold that week at the low, low price of $100, or turned into the TKTS booth for half-off the day of the show. Seems like a win-win situation for them.
No matter how you slice it, $250 for a Broadway show and $450 for a concert is just complete insanity!!
