Then that's not an 8:00am opening, that's a 7:30am opening.
Yes, I know they've been doing that. We actually were at HS for opening day of TSL. We're not rope drop people, not even for opening day of TSL, so we figured we'd show up at 10am and just deal with the insane crowds trying to get into HS. We had a FP+ for SDD, so we weren't worried that we wouldn't get in at all, just figured it'd take an eternity. We showed up at the parking lot around 9am (I forget exact times, but it was a solid hour before the start of our FP+ window) expecting the worst. Imagine our surprise when there was literally nobody in line at the parking ticket booth. We were stunned, but figured certainly we'd hit the mob at security and tap point. Nope. Again, we walked right up and through...even faster than we would on any other regular day. We asked a CM what was going on and that we were expecting a mob. She said "Oh, you should have been here at 5:30am when they opened the gates".
When we were there, it was still an amazingly massive line just to get into TSL, I think they said it was like a 2-3 hour wait. Thankfully, they did a great job with the FP+ line of getting people in. We waited maybe 10 minutes.
