"We believe the Sphere is going to be the most-utilized venue in our portfolio in terms of events. We think the attractions business is going to play multiple times a day, year-round, which is a key part of our strategy." He said that though the company has offered to refund tickets to entertainment and sporting events — its sister company owns the New York Knicks NBA team and the New York Rangers NHL team — about 80 percent of patrons have hung onto their tickets, planning to attend rescheduled events. That's what gives Lustgarten confidence that entertainment will come back strong. With owning Madison Square Garden and its Hulu Theater, the company has Radio City Music Hall and the Beacon Theatre in New York and the Chicago Theatre in Chicago. It expects the Sphere to outperform those venues with daily programming on the massive 160,000-square-foot wraparound screen, headliner performances and an easily accessible site near the Sands Expo and Convention Center for corporate presentations.
