The park has already had thousands of visitors through its gates since it soft-launched on May 17, with many reporting that they enjoyed their first taste of Disney. But the bippity boppety boo didn't appear to be running at full power just yet.
The soft launch was marred by a worse-than-usual version of the universal complaint of all fun-park visitors: long queues, with some visitors reporting wait-times of up to five hours for some rides.
"We got here at 7 o'clock this morning. It's almost 4:00 p.m. now and we only tried out one attraction," one father, who gave his name as Xu, told CNBC on Thursday. "The waiting line is way too long."
Xu was visiting with his wife, Qi, their son, who was wearing a Captain America costume, and Qi's parents. Qi had another complaint: "Stuff is expensive here," she said, noting that the family had spent more than 2,000 yuan ($300).
"We haven't bought souvenirs and eaten dinner [yet]," she said, adding that food in the park, while expensive, was "tasty."
A three-course set meal inside the castle sets visitors back about 368 yuan ($56), per person, without the additional service charge. By comparison, buying a regular Chinese rice dish outside the park costs about 85 yuan ($12.90). Shanghai workers make on average about 4,070 yuan a month ($620).
Despite higher food prices than some locals were accustomed to, visitors queued for as much as two hours to try a traditional American turkey leg for the first time.
One experienced mouseketeer agreed that the wait times far exceeded the norm on the day she visited.
"I have been to Paris Disney and Tokyo Disney. It only took around one hour to get onto a ride, but here in Shanghai, the queues are terribly long," a young girl named Li told CNBC. "I had to wait at least two hours to check out an attraction, at least. This is ridiculous."
However, the grumbles don't appear to have rained on the parade of visitors so far.
Ticket scalpers have been quick to capitalize on the park's popularity, with thousands of soft-launch tickets for sale this week on Alibaba's e-commerce platform Taobao for more than three times the 300 yuan ($45.70) turnstile price.
The tickets had been distributed to the families of Disney staff, Shanghai government departments, Disney's business partners and foreign consulates in China.
One scalper, Jin, told CNBC that he had a family member who worked for one of Disney's local business partners.
"The company bought loads of soft opening tickets at low prices and gave them to its employees and clients," he explained. "I then got the tickets from my relative and her colleagues, some free, some with a few hundred yuan. Then I can easily make big money selling them at a high price again."
Jin said he offered a "booking service," raising the ticket price if the buyer wanted to secure entry on a specific date.
Disney didn't immediately return an emailed request for comment.
