We took it twice this week for “rope drop” with no problems. We lined up at the Epcot station about 8:50, but they didn’t let anyone in until 9:05 each time ( not sure why 9:05 and not 9:00).
We were able to get to DHS, go through health check and security, scan in and get in line for MMRR by about 9:45- 9:50. We were able to get our RotR BGs before boarding Mickey & Minnies Railway. Once the parks start to get busier this strategy may or may not still work.
