I will add to the chorus of folks who say it's worth it if you happen to be there, but don't go out of your way.
My trip two years ago happened to fall right at the last day of FArts and the last of the Disney Broadway concerts so I went to their grand finale show. It was Ashley Brown, Josh Strickland, Kissy Simmons, and Michael James Scott.
I had previously seen the same line up when they did the Disney on Broadway reopening concert at the New Amsterdam. It felt like a higlights reel of that concert overall. Everyone was great and it's fun to be there, but I wouldn't go out of my way for it.
