The water is 84 degrees every day at the Great Wolf indoor water park resort including on Aug. 8.

And why next Tuesday matters is simple.

The resort is offering a limited number of  standard family rooms with two queen size beds for $84 for a flash sale taking place on Aug, 8 or 8/4.

The deal is good for select dales that are Monday through Thursday from Aug. 4 through Dec. 15 of this year.

The standard family room rate midweek can go as high as $499.99 depending on the date and demand.

Such a room at the Manteca resort for a stay from Aug. 22-23 was being offered at $219.99 as of Tuesday at 10 p.m..

An $84 room rate with four people comes to $21 per person, the standard room can accommodate up to 6 people.

That allows waterpark access on the day of arrival and the day of departure.

No outdoor water park can match the rate.

There are nearly 1,000 more rooms available in this year's sale. As usual, there are terms and conditions that apply.

For one day only on August 4 (8/4), rates at all Great Wolf Lodge U.S. locations, including the Great Wolf Lodge Northern California (Manteca), will drop to a starting price of $84 per night (not including taxes & fees) when booked with the promo code 84DEGREES.  

 Based on expected demand, the earlier you try to book on Aug. 8 — such as after the stroke of midnight — the better your chances of securing a room.
