As others have said, avoid the "limited comfort" (no comfort is more accurate) and obstructed column seats at all costs. The regular obstructed view seats are definitely obstructed, but you still have a view of the stage. That said, unless you're shooting for a weekend performance, I would recommend trying rush or using the FUNSAVERS code. I have also seen performances for this engagement on Goldstar. I don't think it is selling as well as they thought it would, so you shouldn't have trouble getting some form of discounted seat, especially for a weeknight.
"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."
