The latest multi-million dollar development on the Las Vegas Strip features a leafy outdoor pedestrian area, 20,000 seat arena, and a small theater.

It’s a move to double-down on events and live entertainment that marks yet another significant pivot away from gambling in Sin City.

This week, MGM Resorts International begins unveiling its $575 million, 22-acre entertainment district on the southern end of Las Vegas Boulevard.

The Park, just off the Las Vegas Strip, officially opened to the public on Monday. It’s between the Monte Carlo and New York New York.

“The trick is we are in Las Vegas, so we wanted to create a micro climate that will make it enjoyable year round, and how do you do that? You have to have mature trees for real shading, you have to have shade structures, but not ugly umbrellas, we wanted something beautiful in and of themselves, and you needed some water, and of course water lowers the ambient temperature in this park,” said Jim Murren, MGM CEO of the project.

The T-Mobile Arena, which will debut Wednesday has lined up a series of high-profile music and sports events on its calendar and hopes it can also be the home of a professional hockey team, should the National Hockey League approve the expansion.
