For networking I would recommend two things. First, if you're doing a CP try taking one of the Professional Development Courses (if they are still doing them, my CP was back in '07) related to the area where you would like to network. I took the one in Finance and was able to meet with lots of professionals in the area, including one executive.
Second, talk with your manager. Now, this one depends a lot on your manager. Many managers will just take too long to set up meetings, or would not be a lot of help. My manager, when I did my PI in '09, was very proactive when it came to networking opportunities for me. She helped me set up meeting with various finance managers, area managers, and two different executives. (She was a great manager, and kind of an exception, but she is not the only one that will do that over at WDW).
Good luck.
