The double sheets are too thin to be the only covers - blankets/comforters need to be added. I agree with all of the complaints about the lack of blankets on the bed. Great view from our room on the 22nd floor. Parking garage a bit of a hike from the hotel - but that's not at all rare in casino resorts. We arrived a bit early and had no problem checking in. The hotel, common areas, etc are very nice since it's all relatively new. It was a family trip to Tulsa - we had our elementary age kids with us.
We went to River Spirit for 5 nights in March.
