Good play with AA?

I don't have the exact hand history with me (at work), but it was fairly straightforward:

Full ring 5NL at Party

Hero UTG dealt AA.
I did my usual 3xBB raise of 0.12 (I'm trying to keep my preflop raises always same lately). Some folds, MP raises to 0.30, MP1 calls. I decide to go all-in as both MP and MP1 have buyin sized stacks. MP calls, MP1 folds. The five cards are laid down and are all low ball rainbow. I win vs his KK.

I realize I won a nice pot, but was this a good situation to go all-in? I figured it was since they both had good sized stacks and I had the best preflop hand.

If you think one of them will call, yes that is a good play. If you don't think one of them will call, reraise it to something like $0.90.

Did you have a full buy-in stack as well? If you did, I think this is over-aggressive at most stakes. I'd re-raise to $1 and push any flop. However, I haven't played anything below 25 NL except in home games, so I don't know quite how fishy they are. If you think this guy is definitely calling with TT-KK, and AK as well, go ahead and push.

Yes I also had a buy in sized stack. I figured he would call based on his earlier play, and if he didn't it was still an easy 0.75 pot steal.
