It’s 29 degrees and sunshine spills like paint across slides rising three stories above the water’s surface. Children splash in constantly rolling waves, and adults melt into a hot spa. It sounds like a scene plucked from the ocean side of Mexico or El Salvador, but this is a moment like any other at Waves Indoor Waterpark at Americana Resort. With a glass exterior, a retractable roof, and year-round temperature controls, the balmy aquatic wonderland brings the fun of the beach to families while removing the risk of crab-shaped tan lines. Tube and body slides beckon speed seekers; sporadic sloshes from the interactive play structure’s giant tipping bucket soak wee ones waiting in anticipation; and the shallows of the kiddie pool help toddlers earn their water wings. To recharge for extended aquatic fun, visitors munch sizzling pizza from the snack bar, or plant their family flags into one of the picnic tables peppering the grounds.
