Live Midnight Tourny -- Time to shove with AQo?

[WhiteKnight]

Second time I've played in this tournament now, the caliber of play seems pretty low, even to someone who doesn't play very many tournaments at all (me!). $30+5 entrance fee, 42 initial players, $1,500 starting chips, blinds increase every 15 minutes. Sorry if this post seems newbish but this is the second tournament I've ever played in.

Up until this point I have voluntarily put money in the pot twice, I completed my SB (blinds 25/50) with A5s after 7 limpers (is this ok?), and raised AA in EP 3x the BB (blinds 50/100) but got no action (do we show our hand here for image related reasons?).

The blinds are now 100/200 and my chip stack is $1,350. I am 3 off the BB, and expect the blinds to increase perhaps 3 or so hands after they pass me. It's folded to me, and I insta-shove AQo. I'm one of the smaller stacks at the table, and there are probably about 20 players remaining. Standard City?
