When we went there last year, we pulled into the Rally Grounds and stayed for two nights. No one came around to register us or collect money. There were only about 40 or so coaches, and we just pulled into a vacant spot near the others. We had 30 amp service and water. Dump Stations were available. We did the plant tour, shopped at the outlet store and picked up a ceiling fan in the parts department. We told them when we registered for the plant tour we were in the Rally Park, and they told us to enjoy our stay! We were impressed at the hospitality!
Spaces around the Visitor's Center are limited (maybe 10?) and first-come-first-served, and used by folks getting service work done at Winnebago. The Rally Park is huge and filled during the Grand Nationals, but mostly vacant at other times.
