LOS ANGELES (CBS) — Hundreds of patients at Childrens Hospital Los Angeles woke up in a new $636 million facility Monday morning.

Doctors and nurses moved 200 children to the seven-story, 460,000-square-foot building on Sunday.

Nurses say each move to the Marion and John E. Anderson Pavilion, which has 40 percent more bed space to accommodate current and new patients, was carefully choreographed.

The rooms also have family zones, which allow relatives to stay overnight.
