If you live in South Florida contact AeroStar, I believe they will let you observe an A320 sim training session for a few hundred $. Or if your company has a jumpseat capability, try and catch a ride on one.

Might be worth it, but as a previous poster suggested. Go to a regional especially one with E170/175's. I transitioned from C172 G1000 to Caravan G1000 to Embraer E175. I've jumpseated on older A320's and looks like my E175 FO job easier.
