ugh, I just spent 4 hours on a MSP layover..Didn't even think to check this thread or the website to see the PGA lounge is on there now..

oh well, I found a quiet seating area up on the 2nd floor past the escape lounge, down the hallway that looks like all offices, it opens up above the main floor (kind of looks over the coal fire pizza place), so it's not really quiet, but fairly comfy chairs/ottomans and nobody there for the most part. They even had sleeping mats for I guess when things go south during the winter and flights get cancelled.
