My brother and his family just returned. I had told them about Josh on Easy WDW reporting that people were being let in earlier than 7:00. So, he and his family arrived at 6:15am were in shortly after 6:20am I believe. They only opened up TSL at 6:20am ish (not any other part of the park). They rode Slinky Dog and did a meet and greet and Alien ride easily. I think they did the Alien ride twice - all of this in about an hour or so. This is our plan when we go August 10th. I'm hoping to get there early and get a couple of quick rides, although we did get a Slinky dog FP for one day of our trip. He said it was painless - not many people there before 6:15am, so not a huge crowd to contend with ... but l'm sure it got much busier.
