Price Insights for Sports Illustrated Resorts Chicago

• Lowest Price Period: Late March to early April (notably March 31 is the single lowest price at $179). Other consistently low periods are mid-December (many nights $199–$249) and several mid-week dates in April ($189–$234).
• Potential Savings: Up to about $800/night comparing the absolute low ($179 on 2026-03-31) to the peak highs (e.g., $979 on 2026-05-29 and 05-30). More typical savings of $100–$300 can be achieved by moving a stay from a busy weekend/holiday spike into an off-peak mid-week date (for example, $309 nights in mid-April vs $179–$209 in late March).
• Average Rate: Average listed rate across the provided dates is approximately $350/night (rounding to nearest ten dollars), with large variance due to multiple high spikes in late May, September and summer.
• Booking Tip: If your dates are flexible, target late March–early April or mid-December for the best baseline rates; avoid late May, mid-September and some summer holiday weekends where prices spike. Use flexible-date search and set price alerts, book refundable rates if you want to rebook after a drop, and book 30–90+ days ahead for event-heavy dates while last-minute deals may appear for true off-peak mid-week nights.
