Seeing as how we have never had a problem with leaving our stuff in a stroller outside of a ride, I've never felt like the cubbies were any less safe; in fact, I've always felt they were MORE safe because they're where employees can see them.
I think SDC should look into possibly installing loose article pouches ON the rides, like some Disney rides have. It'd keep people's items close at hand, secure, and it'd move people through the rides a bit faster because they wouldn't have to walk THROUGH the ride to get to the cubbies, and then back to get seated. They can just stuff their things in a secure pouch in front of them and get seated.
