Navigating Star Wars area

[lookame]

So we’ll be doing Hollywood studios one day on our trip. We stayed up and we’re able to snag a savis reservation at 8:45 am for 3 people in our party and anouther 3 reservations for droid depot at 8:40 am and another at 9:10 am (this one could be moved to a later time…it deals with one in our party doing both savis and droid depot). So we have these reservations as it was important for savis and the earliest time was the only ones we could get. So the question is…how do we navigate the more popular rides with these in place? Being that savis and droid depot are pre park opening reservations and we have a party of 10 would all of us be able to get into the park or only 1 builder plus 1 guest? Also, we were in such a rush that a few of the savis are under the same builder or the incorrect builder, is it an issue if the person who the build is under checks in and pays but a different person builds?
