My wife and I arrived without reservations a little after midnight on a Saturday night. Hotel was hosting a wedding party, but we checked to see if we could get a room.
The clerk was very helpful in putting us in a ground room floor, away from noise, and gave us a nice discount (because the room probably wasn't going to be used unless we did).
Wi-fi worked well. Breadfast was the standard hot-breakfast fare available at many restaurants.
We'd stayed here years ago with a fastpitch softball team and had similar service. Great place to stay when visiting the Sioux Falls area or needing a place to stop on I-90.
