The developer of the 1,500-room Gaylord Rockies Hotel and Conference Center made a big splash Thursday, saying it would add a massive water park to the project near Denver International Airport.

The indoor-outdoor water park will feature multiple pools, two water slides, a lazy river and a simulated hot springs, Houston-based RIDA Development Corp. announced Thursday.

"It brings a magical connection between leisure business and group business," said Nunzio DeSantis, director of hospitality with Dallas-based HKS, the architectural firm designing the development.
