Biologists estimate that water makes up 65% of the human body, 71% of the planet’s surface, and 0% of the R & B group Earth, Wind & Fire. Conquer the planet’s most prevalent liquid with today’s Groupon to Ray’s Splash Planet. Choose between the following options:

• For $4, you get one child, adult, or senior admission (up to an $11 value).
• For $16, you get four child, adult, or senior admissions (up to a $44 value).<p>

A parent or guardian must accompany children younger than 3 at all times and children younger than 10 in the pool area; guardians must have their own ticket.

Ray’s Splash Planet’s 29,000-square-foot, climate-controlled facility churns 117,000 gallons of water through sundry slippery attractions. After dipping toes into the gradually descending pool at Moon Beach, children and their pet raisins can fully hydrate at the Saturation Station, where water geysers stand watch over four slick slides. Meteor-like showers of clear soup fall down spontaneously to keep swimmers on the toes of their flippers, and the park’s centerpiece—a three-story water slide—challenges the bravest guests to whip through its double figure-8 while being chased by R. L. Stine.

For a more low-key experience, adults are free to tube ride down the gently flowing Orbiter canal or venture to the Sea of Tranquility, where lanes allow swimmers space to hone doggy-paddle technique and basketball hoops facilitate water sports, such as golf.
