Can I use 2 TV's as secondary displays from Macbook Air?

Here is what I need to be able to do:

In one large room, I need to display my keynote presentation from my Macbook Air 11" (Mid 2012) onto 2 50" Flat-Screen TV's simultaneously that are on the walls on the left and right sides of the room.

I have several Apple TV's but don't really like Airplay so much because it looks "choppy" when displaying animations. Besides, I'm not even sure you can Airplay mirror to 2 Apple TV's at the same time...?..

I also am wondering... will a Thunderbolt-to-Dual HDMI Out work (or does that exist, lol) ??

Help much appreciated..
