OK, I like DTW a lot too, BUT, there are two (related) problems with it -

1) The meditation room is terrible! Its hard to find, its via an elevator that implies only staff can ride it, and down a long, non-descript corridor into an ugly room that doesn't feel... inspiring of meditation, for sure.

2) There is no airport observation room like there is at MSP (or at least I haven't found it yet - is there one somewhere at DTW?)

Now, I haven't checked on MSP's meditation room (is there one?) but with the airport observation room I don't need to (and don't ask why....)
