If you want to check out the new Great Wolf Lodge but you need to stick to a budget, mark your calendar for Aug. 4.

For one day only, the family-focused chain will slash rates at its resorts nationwide, with some rooms starting as low as $84 a night. The price mirrors the 84-degree temperature to which the chain's signature indoor water parks are climate controlled.

Great Wolf Lodge has resorts in 17 cities across the United States and Canada, with another resort opening in Scottsdale, Arizona, Sept. 27, reports The Arizona Republic, which is part of the USA TODAY Network.

The one-day sale only applies to U.S. locations.

How to book: Call 844-473-9653 or book online at greatwolf.com. Either way, use the promo code 84DEGREES.

Fine print: The sale is on Aug. 4 only. It's good at all Great Wolf Lodge locations for stays on Sunday through Thursday nights from Sept. 2 through Oct. 31. Blackout dates apply.
