Do any non-Orthodox people do the week long shiva anymore? Do all orthodox people?

When we lost my parents, both in the last ten years, it was just one night for both of them. When I was growing up we went to a Conservative synagogue. This was not any philosophical decision, it was just that there weren’t all these people who were going to come from out of town in later days or locals who would visit repeatedly if we did it for more than one night. We still called it a shiva even though it was one night. I didn’t really think about it too much, but I am curious.
