Light In The Piazza Closing Mania?

So, here's the deal...I'll be in NYC this weekend. My aunt and I are braving the TKTS booth during tourist season on Sunday afternoon, so that I can have a chance of seeing The Light In The Piazza before it closes. My question is, is there the 'closing mania' that sometimes happens when shows close? By that, I mean, does everyone go, "oh ****, I'd better see this before it closes!" and rush out to get tickets? I really hope not, because I really want to see this!
