New Fantasyland didn't stand a chance against Harry Potter. Right out of the gate it should have been clear Potter was going to be the winner.
I always been under the impression that New Fantasyland was not the answer against Harry Potter. I thought Pandora was more of an Answer against Potter. It seemed to me Disney wanted more capacity for MK. What Disney had for the New Fantasyland Expansion was changed between chairman of the parks. The one in 2009 was supposed have a big Pixie Hollow meet and great instead of Storybook Circus land and there was no Snow White Mine Train. All the plans were dueling Dumbos, little mermaid ride with shop, and a Beauty and Beauty mini land without a ride.
Disney at the time New Fantasyland was announced seemed to be the wrong move from the start. WDW in 2009 had major problems at DHS and Epcot. I know DHS had Toy Story Midway Mania open in 2008 and American Idol Experience open in 2009. The catch is Idol did not meet Disney's expectations. I know nothing could have been done for a Star Wars land at the time, but Disney had a chance for a Pixar Place expansion. DHS in 2009 had a Studios Backlot Tour that seen its better days. Lights, Motor, Actions was not a great addition Eisner pulled. LMA is not a show that people in the mid afternoon want to see in the hot summer sun besides being a one and done show.
Epcot in 2009 already had issues with Imagination, Innovations, and Ellen was already very long in the tooth in 2009.
To me what made matters worse for New Fantasy Land is the content. I thought back in 2009 that Beauty and the Beast mini land was not what MK needed considering that mini land had shops, 2 eating places and an interactive meet and greet in Belle's Enchanted Tales. MK in 2009 did need more capacity, but it needed something like a theater, or more rides. The problem is Eating places, shops, and interactive meet and greets are not high capacity items.
The Little Mermaid ride was a mixed bag. The rock worked looked great, but the inside was the issue. The story telling of the ride was disjointed besides parts of the DCA version was changed just a couple years after it opened. That showed Little mermaid was flawed ride from the start. Mine Train is a nice ride only if you have a fast pass plus or wait times are not bad. Story Book Circus land was well themed, but you can tell that section was done cheap like the Circus themed goofy Coaster. The fact is the Goofy coaster was not changed outside of overlays. The money of Storybook want to Dumbo's queue.
