MSP works, despite the layout. As someone who is physically fit and doesn't mind walking, it doesn't bother me.
F can get a bit crowded a times, and I really don't care for the F Skyclub, the rest of MSP is great.
I've been booking a 30 minute connection through MSP, which involves a mainline -> RJ connection and made it every time. Granted I'm right at MCT so I'm playing with fire, but I honestly don't care if I miss it since I can always catch a later flight in the day.
This morning arrived at F4, departed from B4, made it in 15 minutes just walking/moving sidewalks and no tram, including a restroom pit stop.
Usually my flight in from DTW arrives at C/D but occasionally its F.
Its one of the longest treks and shortest connection times and it works. Granted when I have 1+ hour on the return flight, its a cake walk.
I also much prefer the C SkyClub since its quieter, has better seating options, better decor, and better outside views.
