I just received one for the parks we visited last week. Unfortunately they ask specific questions but didn't provide any space to comment on things outside of the questions.
Maybe it's just OKW that doesn't send them. We stayed there from April 27-May 6, and never received any satisfaction survey. Maybe that's because they knew how Unsatisfied we were with Olivia's Mobile Order. But they would have gotten very high marks for our room and location.
