Bedtime for 16 year old???

[rainbowkids]

Advice needed please? My dh and I can't agree on the right bedtime for our dd. She's 16 and goes to college. Dh says we need to keep her bedtime for 10pm weekdays and midnight on a weekend and holidays. She only goes to college on Mon, Tue and Wed.
Can I please ask what everyone thinks? Is this too strict or the right thing to do? Advice please?

What time does she have to get up for college, and what's she like in the morning?
If she can go to bed at 10 and get up on time and be ready for college then fine. But if she needs waking or is often late I'd go earlier. 10 is our very latest for teenage DC during the week, and only on days when they have a club that is on late.
