What are the barracks like at Fort Riley for 11Bs?

Riley B's are mostly decent since they were built semi-recently - two bedrooms with a shared kitchen area/bathroom. Expect some minor issues like heating/ac problems in a couple rooms or, most commonly, the electronic door locks to be broken or run down, and that's just an easy battery replacement to fix. For the most part they have decent amounts of room and are pretty comfortable.
That said, you might get lucky and end up in the old barracks, aka 'overflow barracks,' which are something like 2-4 dudes to a room, bunks and wall lockers, with a couple community bathrooms per floor. I've never heard anything positive about them. Cross your fingers.

Can't help you on the Riley never been there but I have heard good stuff about it. Bliss is actually pretty awesome. I'm hoping if I can't get Germany ill get Bliss.
