@PolDisneyfam My plan is to arrive by 12:01 on 8/29 (picked that time to be extra clear)
As far as "camping out" from previous experience doing Star Wars Weekends we were allowed to bring foldable chairs, sleeping bags, small cots, some people even brought small tents, about 3 hours before opening every day we were told to take everything back to the car
As far as holding spots we would arrive real early (2am for me most days) and then kids could join us with another adult before they gave out wristbands for celeb autographs, this was done again about 2 hours before park opening so everyone had to be in line by then.
Not sure how Disney would feel about people just tossing/leaving chairs behind but you'll ding locals able to take them back to their cars
Now Disney didn't want people camping out but LucasFilm insisted they allow people to do this as this is sort of the SW fan experience. LucasFilm still has a big say even though Disney owns it now, but as long as Disney doesn't come out saying "NO CAMPING" most people are thinking of doing it
