No I've never had to enforce a bedtime with my kids. While my kids were asking to be tucked in at 7pm, my brother was just gearing up for the 5 hour battle ahead

Even now as teens, I never say anything about bedtime and my house is quiet by 11 on weeknights, maybe a bit later on weekends. Mornings are not a struggle, I don't have to do wake up calls for anyone. They all have tvs/computers/phones in their rooms but there's never been a video game or tv show that is interesting enough to them to lose sleep over. My brother on the hand has the "common area only" tv/computer rule and he's in a constant battle with his teen boys about them and bedtime. So I guess it's just depends on the kids' personalities.
Joe I think if your daughter is responsible and a good student, there is no problem in letting her control her own bedtime. She's safe and in your house, which is the most important thing
