I don't see them cutting it altogether, but anything from the simple (swapping Sunday for Friday) to the complex (some type of dreaded reservation system) seems possible.
But the obvious answer remains obnoxiously huge price increases, to make up for years of refusing to budge on that issue. I know back in spec season Brian argued there's a ceiling, but honestly it feels like we're on the 50-yard-line and that ceiling is the Texas Dome. When MNSSHP gets more for a single night than a FFP, you need a major re-evaluation. Honestly for the best, not just revenue-wise -- if kids can only go once or twice a season, makes the event more special, doesn't risk becoming the equivalent of hanging at the mall in the 80s..
Honestly, if they took the budgets from SF and Central Park, no one outside these boards would miss those zones at this point. Too crowded to function even on medium nights.
