Vacation rentals in South Park

I want to make sure I’m accurate, but I can’t find an officially incorporated city named “South Park, Illinois.” Could you confirm the exact location (e.g., the county or nearby city) or share a link? Once you confirm, I’ll draft a concise 2–3 sentence, fact-based blurb suitable for a vacation rental page. If you meant a different place (a neighborhood or a similarly named town), I can tailor it accordingly.
