Are there any Cubs season ticket holders out there?

After being on the wait list for 6 years I received a phone call this year telling me to come on down and select some seats. While excited, I would not have minded waiting an extra year or two before committing, but I had to do it while I had the opportunity.

While selecting my seats the saleswomen told me that it would be no problem for me to call my Season Ticket Rep and he would be able to set me up with additional tickets to a game if needed. I'm wondering how easy it is to do this? Any advice is much appreciated!
