I edited the above post with my experience, but here are some other notes.
There was one other section where people were “camped out” all day. I believe these spots go first. I walked by a little after noon to stretch my legs, and it looked like this:

So this is the area where I was. I am friends with several of the people camped out there. They got me back in just after the first parade and just before the crush of everyone coming in standby. I had to leave midday to see my parents (one in hospital and the other in a board and care), but got back during the parade and thankfully was able to join my friends again. I sat on the ground next to one of the benches, so could not see a lot, but still enjoyed it again. There were less benches than in years past this year for this section.
