if i get aces i always look to see whos left in the hand and what kind of stack they all have. i also recall how they have been playing loose tight but if i was late to act with some loose callers ima bet 5x bb i play alot cheap mtt and fr so i might even bet more. if i was in early pos and there was aggressive players after me i might raise 2-3x bb could even limp if i thought there would be a raiser.
