We have stayed aft on both the Dream and Fantasy (just last week - Cabin 6668). Outside of when docking at a port, I really cannot say I noticed any vibrations. When they dock and use the thrusters and reverse the propellers the whole ship vibrates, so I don't think that should be a big concern.
Advantages - virtually never have to wait for an elevator (I avoid mid-ship elevators like the plague); one floor down and short walk to the kid's clubs; two floors down to the bars; three floors down to Animators and Royal Court.
Cons - elevators dump right into Cabanas. Still the most odd thing in the design.
If I have to go from aft to mid or forward I always either go to 4 and walk outside or up to 11 and along the pool deck. Way better than the narrow and twisting hallways.
