Some thoughts:
We had a pretty consistent 10mph wind from the east today. The affect on air flow in the cabins was very pronounced. Heading west out of Riviera, there was almost no airflow, and it became a bit uncomfortable. It improved as soon as the cabin made the turn north towards Epcot, even before it picked up speed. The cabin was quite comfortable when traveling in all other directions. Even heading south, with the wind blowing against the windowless doors, there was a good breeze coming up from the floor vents (which I can't figure out, because they're only on the back of the cabin.) Indeed, at times the wind was whistling through like a log cabin on the prairie.
I was riding on my ECV. The cabins also got a bit uncomfortable in the stations, but I attribute that to the fact that the wheelchair cabins spend a lot more time in the stations, much of it with the doors closed. There's no perceptible airflow when the cabins are moving at load speed.
The cabins seem to pick up and amplify sounds from the ground. I guess the sounds are bouncing around the walls. Passing over BVD sounded almost like NYC traffic. The roar of the BWV air conditioners was very noticeable, as was the noise of any construction machinery that we happened to pass by.
The solar panels along the paths between Speedway and the firehouse and through the woods on the Studios line are there to power small lights along the paths. I noticed the lights along the Pop/AoA path, too, but I didn't see any solar panels there. I guess they have electric service.
Lines at the CBR station seemed to build throughout the day. As others have said, they were a tangled mess, especially the line for Epcot, which overflowed both the permanent queue and the extension taped out on the floor. It made getting to the restrooms difficult.
Wheelchair entrance to the Pop station is thru the exit. Weird.
CM's said it's perfectly OK to request an unwrapped cabin, even in the wheelchair line. But it may take a while on the wheelchair line, because there may be only 1 or 2 unwrapped cabins assigned.
People on the board were wondering how the spurs to the storage yard connect to the main track at a 90 degree angle. It's simply 2 small radius curve tracks on both sides, with switches and a chain drive.

The CBR internal shuttle bus stops at the Skyliner station in both directions, between Trinidad and Jamaica, and on the return from Aruba to Martinique. The number of buses on the route has been increased from 1 to 2, so they're probably running about every 10 minutes.
I noticed the walkway from the bus stop to the storage yard didn't have any restrictive signs, so I rolled up and peeked thru the fence. Very interesting. A chain drive moves cabins across the top of the yard. Drive tires move them thru the switches onto the individual legs -- just the opposite of the switch into the wheelchair platforms. Those boxes seen above the middle of the legs in the overhead photos shelter another set of drive tires.

ETA: Forgot to mention: I saw a gaggle of Doppelmayr techs hobnobbing at CBR. I think they were the ones hired for local support. They were wearing an assortment of various-colored ordinary work clothes, with a Doppelmayr patch above the breast pocket, a Skyliner patch on one sleeve, and a nametag (did
