Does this raise scream of aces?

[se2schul]

This is a Party $22. I know I made the right play, but how should this hand be played at the higher levels, namely $55-$215?

UTG raises to 100. I have KK, which I'm obviously not folding preflop. I can't shake the feeling that the raiser has AA, but I'd make that same raise with QQ-AA. I called and doubled up, but it got me thinking... Do you higher level players give people more credit at the higher levels? For example, if I were holding QQ would it be right to fold at the higher levels in this situation?

BTW, you really can't give the $22 players much credit. I'm not even done typing this post, I've already quadrupled up, and the BB is still 30.
