I would rather do a virtual queue than stand and wait for a long time, but I'm pretty sure there will be people there at 6 AM. I wasn't saying how I felt, just trying to think of why some people might still want to get up early and get there for 6 AM. In fact, my family is so spoiled we won't wait for anything longer than 20-30 min except in extreme circumstances (Like a brand new ride), and even then our limit is in the hour range, we typically don't wait loner than 10-15 for anything. We just use FP and less crowded rides, and if we miss some we figure we'll get them next time.
Based on DL you would be able to book Oga's and Savi's, I didn't think the droid factory had anything to book in advance. We are doing the very first AP preview, but didn't get oga's or Savi's, so I hope to make a droid, try some snacks/quick service food, try the blue and green milk, ride the ride, and take tons of photos. My 2 boys will only be on board with the Droid, ride, and snacks, lol, they couldn't care less about photos and seeing all of the detail. Then who knows when we'll be back, even with ROTR we won't wait hours for a ride, but as you said we will wait in a virtual queue to get into the land. We'll have to see how things are going come next spring/summer.
