I've stood a few times on Broadway, as well as at The Met. I agree with Kad. Of course, I'd rather have a seat. But if there's a show I'm dying to see and the only way to see it would be stand or pay full/premium price, I'll happily stand.
I've found that my standing experience really depends on how much I enjoy the show. Standing for
The History Boys was a dreadful experience, mostly because I hated the play.
Spamalot, on the other hand, was a breezy, fun standing experience. I've stood for 4 hour opera at The Met that just flew by.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
