I might be an exception to the rule because I am a morning person while considering myself being creative. Although that might simply be because I've adapted to the 9-5 (or 8-4 at the moment) rhythm due to necessary.
But I still strongly resonate with having that peace at night and during summer holidays I noticed my sleeping pattern shifted couple hours forward (waking at 9-10 AM) from the usual school schedules. But my body seems to be bio-mechanically strict and it wants to wake me up early and consistently at the same time; I think the times I have woken after noon are countable with fingers only, and those were while in my (early) teens. If I stay up later than usual it almost always results with lack of sleep because I can't sleep long in the morning.
