Major sponsors (and their families) MAY receive discounts OR special benefits. I would suggest asking your Human Resource office at work.
For example, I have been to the lounge overlooking Test Track in Epcot a few times courtesy of GM employees and/or retirees. I have also dined at Club 33 in Disneyland California courtesy of Kodak employees. Nestle employees receive similar lounge access at the Land in Epcot.
