There won't be any repeating songs, but that doesn't mean there's no reason to see more than one show. Different experiences. However, I totally get why someone would only care to see the show once.
I know for me, Images and Words is my all time favorite album for any band. Learning To Live is my favorite DT track. I've never seen them play that song out of the 14 times seeing them. I think this is the last opportunity for me to check out some of these tracks live, including ACOS. So I find value in seeing the show multiple times. But that's just me, I'm also really into seeing concerts and enjoying the live experience being part of the crowd, cheering, having fun with random people, and whatnot. Not everyone is into that.
