I know this is not the most exciting topic, but I will be in Sioux Falls, SD in Sept/Oct for a few weeks and am trying to pick hotels. It seems to be between the Courtyard, Springhill Suites or Fairfied. I dont want the Residence or Townplace for lesser points.

Usually I would think Fairfield is the least favorable but after staying a the Fairfield in Santa Cruz, they can be pretty nice if newly renovated. I have never stayed in a Springhill and it seems the main difference are the room configurations. How do these compare to Courtyards? Oh and I am a Platinum member if that helps.
