Full of energy at 10am is a stretch. Most of them aren't getting to sleep until well after 3 am, as late as 4 am by the time they clean up. If you show up at 10 am, most are still either getting out of the shower or still fixing their hair or makeup. Even with my ATF, I prefer no earlier than 10:30 am, and even then I might get her without her makeup being applied.
