Yes, obviously Cars Land and the radical remake of Buena Vista Street is not cheap. Heck, it all looks like the most lavish and expensive thing to hit Anaheim in decades!
But another thing to remember is the incredible lineup of beefed up and top-quality entertainment headed our way this summer; Mad T Party (that is already looking far more lavish than elecTRONica or Glow Fest did), plus Five and Dime, Citizens of Buena Vista Street, daytime Paradise Bay fountain shows, Red Car Newsboys, DJ dance parties in Cars Land, Red To The Rescue shows in Cars Land, Minnie's Fly Girls, PLUS five (5) Alladin shows per day seven days per week, PLUS two (2) Pixar Play Parades per day seven days per week, plus a revamped World of Color twice per night, and all the other DCA enterainment or attractions that is fresh and hip and introduced recently or coming this summer (Phineas and Ferb, Little Mermaid Ride 2.0, Paradise Garden bands, Mater's Tall Tales in Blue Sky Cellar, etc.)
And then there's Disneyland with two (2) fabulously upgraded Fantasmic shows per night seven days per week, one of the best fireworks spectaculars in any Disney park nightly, a revamped summer version of Magic Memories and You, two (2) Mickey's Soundsational Parades seven days per week, Tomorrowland Terrace dance bands, Big Thunder Ranch Jamboree, Matterhorn Mountain Climbers, Voices of Liberty in the Lincoln Theater, upgraded Main Street USA restaurants and shops, yet another summer of All-American College Band (that WDW management cut a decade ago), etc., etc., etc.
All that they have added and plussed and upgraded at the Disneyland Resort in the last 12 months (or that's coming in the next 30 days) warrants this latest price increase. But then you plop Cars Land and Buena Vista Street on top of all that, with four new rides, and it's actually a minor miracle that the increase was this small.
And again, this is the free enterprise system at work here. If they weren't selling a superior product with a line of satisfied customers willing to buy it, they wouldn't have raised the prices.
