My partner rushed for us. He's a student, and they do check IDs, although they barely glanced at it. Our seats were in Row C of the orchestra (which is the second row at this theatre), house left, the furthest seats on the far aisle. For a different production these seats would probably be considered partial view, but we didn't miss anything, save for the performers' backs being to us at times. The people behind us in line were seated directly behind us in Row D, so I imagine they use rush to sell the sides of the orchestra.
I doubt you'd have much trouble getting in. We rushed at 4pm for a 7pm curtain and didn't have any trouble.
"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."
