To answer some of the questions that were floating around...
For context, usually in the morning you are very limited on time (unless you wake up before reveille). You'll hear the call at 0500 and post out in the hallway for muster and then you'll only have about 10 minutes to get dressed and ready for PT. This gives you time to shave, but not really time to shower. Most of the showering is done in the evening after chow once things settle down.
For shaving, if your hair grows fast, consider bringing a manual razor and an electric. I know a few guys who would get a good shave before bed and then touch it up in the morning with the electric. Seemed to work out just fine.
After evening chow, there aren't really many events going on. This is the time that people spend shining boots, prepping uniforms, studying, writing letters, showering, sweepers, etc. You'll do a passdown where you'll meet as a class (or company) and do the section leader turnover and talk about any relevant information too. Taps is at 2200 and I think technically you're supposed to be "lights out", but plenty of people stay up past taps if they have more studying or prep to do.
