Easy. Price is another thing. Figure $200 for shared and up. Higher for single room. Collierville and Germantown are safe. Horn Lake and Southaven are safe. If you are not sure where it is safe, ask around.
In the AOC, there are also crashpad listings in the new "locker" area on the back side of the bins, out of sight so you have to look for them.
Best place is break rooms in Module D, in the MD-11 wing. I am not sure if there are any in the "new" wing.
