Training Validated. The night is uneventful for the trainers, and they wake up in the morning well-rested.
Wake whenever. Since most of you went to bed around 8:00 PM, you can wake up as early as 4:00 AM. Collin spent a couple more hours training, so he waits until 6:00 AM minimum. You'll have a bit of free time in the morning before stuff starts happening, depending on when you choose to wake up.
