Based on research and other tools it appeared this would be a good bet. Checked priceline.Express Deals and they had a 3* for $53/night in Lincoln-Airport. Ended up being Country Inn North, very important difference between this and the Airport one.
Started bidding at $55 for 3* in West Des Moines and had a counteroffer come in at $70. Accpeted it and the hotel was a 3.5* for Sheraton West Des Moines. Although you have to pay $10/day for internet I'm still saving over $70 per night. Free parking too!
Started bidding on 3* for the date listed. 65 75 85 90 95 100 105 $105 was accepted for a 3.5* I never changed zones or dates since I'm in Boulder on that date.
