Nope, they won't deny you one. Just don't use the head (toilet) during RLP morning or your hatch match (roommate) will probably kill you. They are suit style barracks (dorms). Each hatch (room) has 2 racks (beds), 2 desk, 2 foot lockers, 2 really large lockers (size of a mini closet), a sink and vanity, and a private head (toilet). There will be an identical hatch(room) that will be connect by a shower room with 2 private showers. At night you keep your door and blinds closed. You can use the head whenever you would like at night. RDCs and DIs will honestly give you uninterrupted sleep from 10pm-5am every single day. The only exceptions to this will be about when you are a candio and have to set up evolutions for the indocs or 4-5 times when you get scheduled for the night watch shift (4 hour shifts) 2200-200 sucks because you still have to PT even though you only got 3 hours of sleep, but 200-600 isn't bad because even though you only got 4 hours of sleep you don't have to PT.

MAKE SURE YOU KEEP EVERYTHING LOCKED AT ALL TIMES.
