I got to see (what are likely my last) views of the River last night. The walls still have a decent chunk open, but likely not for long. I will give warning - the walls do make navigating during Starlight a bit worse. Obviously, it's the same physical space mostly. But, people sort of move away from the walls, so it did seem to squeeze traffic moving back and forth behind the viewers a bit more squished. So, plan accordingly if you're going to try and get to/from Tiana's or BTMRR during the parade!
(I actually heard a number of people talking about the plans. The word "Why" came up a lot. Interestingly, it was mostly Brits.)
