Question about Shipout

So I’m at the Meps hotel and I ship out tomorrow from MEPS, I’ve already checked into my room and gotten my key card. Theoretically if I was to miss the 20:30 meeting but still return before the 10:00 curfew what would happen? Would it be bad? I’m trying to meet with a friend who is moving and I’m joining the military, they live an hour away from the Meps hotel.
