Looks like it's time for $pa¢e to crunch some numbers to see if a BK roundtrip is worth the $14 savings.
You're assuming I'd ask my Brooklyn friends for a place to crash (I wouldn't), assuming their place was big enough for guests (it's not.) And that my family would want to go (they wouldn't, at least not to the show.)
But yeah, if we didn't have other travel booked, I'd try to integrate free music into an NYC trip.
