We did DHS last weekend, we arrived just before 8:30 am in time for them to open the turnstiles. We rushed in expecting to be corraled but were not. I can tell you having participated in the running of the tourists on the way to TSM, this was a much better system. More importantly it was SAFER!! Nobody being trampled or pushed to the ground, no massive line ups at the fast pass kiosks.
I hope they keep this opening style at the Studios, it made for a much more pleasant start to our day!!
