The Holiday Inn in Elmhurst (just minutes off Interstate 290) is home to 24,000 square feet of wet and wild fun for all ages. Tube rides, a plunge pool, a vortex pool, a zero–depth interactive playstation, and a dumping bucket welcome you year–round. Mayan Adventure is Chicagoland’s first water park, and, according to families who return again and again, is still a thrill a minute.
