I came across an article that indicates Disneyland is removing in-park benches. The effort is reportedly part of a plan to address current overcrowding issues and to make extra room for the massive crowds expected when the new Star Wars: Galaxy's Edge opens at Disneyland in summer 2019.
Visitors may also notice the park has already removed many of the brick planters that some use for seating.

I always find one of the great things about Disney I just sitting and people watching and enjoying a break. I wonder if this will come to WDW unless it already has and I didn't notice, or maybe there aren't that many benches in the first place).
