Animation. That's where the need is. That gets people to the right side a bit more and helps out a fairly dated and underutilized area. There's really only one expansion spot on actual Sunset Blvd. That is unless they decide to demolish BatB or even Fantasmic someday. And while it may seem like blasphemy to some to demo Fantasmic, it HAS been talked about. It was where Tron was supposed to go before it got put in MK.
Yeah, Animation Courtyard would work as well.
