Are we tho? Peak nights for MNSSHP are $200. Non-peak nights for Jollywood Nights start north of $140 with an AP. Even assuming the advertised lower crowds are equivalent to HHN Express (a bit of a stretch), you can get 20 nights of HHN with Express for roughly 3 at WDW. Day tickets and APs for both parks are nowhere near that far apart. Becomes even crazier if we compare non-Express multinight tickets.
The $50-ish price hike last year didn't seem to reduce crowds by a noticeable level. And the Mouse keeps doing parties, so they must sell decently. I think we're nowhere near the ceiling where lost ticket/beer sales > additional revenue from price hikes.
