Shanghai Disney Resort began a six-week pre-opening series of trial operations on Friday.

“A trial operations period is a key pre-opening step for all Walt Disney Parks and Resorts destinations and major attractions around the world. At Shanghai Disney Resort, the trial operations period allows invited participants to experience select attractions, entertainment and dining on select dates,” the company said.

Until the June 16 opening participants will be strictly by invitation only and mostly limited to Shanghai Disney Resort ‘cast members’ and select resort partners and stakeholders. And not all offerings will be available during the trial period.
