Oddly it doesn't really detract from the experience when you are there. The pictures online often show quite imposing walls and blockages. However on the ground it feels very different.
The castle stage isn't well used. The hub has been the focus for many years. The storybook area at the back of the park is often closed during slower periods anyway. Space mountain is still running despite being walled. The paving in Fantasyland is incremental.
In WDS, the walls initially seem big but they quickly navigate you round them. I actually enjoy the side path to what was the old Studio 1. Once you're past the first lot, the expansion wasn't an area you could have went to anyway.
So ultimately despite lots of activity - theres not a lot of stuff off the programme or 'in the way'. Making it quite easy to not be bothered by.
The Village and security tents - I have literally no idea what they're up to. They've been refurbishing the fences and tents/bag scanners continuously for 15 years now and I suspect they'll immediately start again - given the nice new security scanners they have at WDW are faster and require less staff.
